There is something missing from our world. The amazing creatures that time has left behind. But what if we could bring them back?

What if extinction didn't have to be forever?

We're going back in time on a safari with a difference as wildlife adventurer Nigel Marvin plunges into prehistory to rescue creatures on the brink of extinction. His plan is to bring them back to the safety of the present and give them a second chance.

On his very first mission, he hopes to rescue one of the last of the dinosaurs from the most dramatic extinction ever.

Welcome to the ultimate wildlife sanctuary.

Welcome to Prehistoric Park.

It's a very big day at Prehistoric Park. All over the park, final preparations are made for every exhibit. These will house everything from giants bugs to dinosaurs.

Nigel is sitting next to his jeep, parked on a hillside, looking at a map of the island that houses the park.

"There's so many habits here, all of them suited to different creatures. To the South there's an ocean and to the North, there's a mountain range. In between, there's rivers, lakes, plains, forests, deserts, snow fields (somehow), and even a waterfall."

If Nigel can make prehistoric animals at home anywhere, its here.

Nigel has left Prehistoric Park and is now in a Museum.

One day, Nigel plans to bring back breeding populations of prehistoric creatures. For now, though, he only plans to bring back a few of each species, to see how they do in the present.

And he already knows which one he wants first.

Nigel has come to a stop in front of a skeleton: that of T. rex.

Nigel's returned to the park and is busy working in his den.

"The first animal I want in Prehistoric Park is T. rex. If we can handle one of them, then we can handle anything. And " (points to a map of Earth in the Late Cretaceous Period (Maatriscian(?) period) " I know just where to find them: Late Cretaceous North America, 66 million years ago. Now, see, most scientists believe that, at that time, a meteor slammed into the Earth in what is now Mexico, which caused the extinction of the dinosaurs. So I'm going to go back and try to rescue a T. rex before the meteor hits."

Nigel's plan leaves little margin for error, as does his targets. One mistake and the park may never be. For Nigel, though, the risk is worth the reward.

Nigel has arrived in Prehistoric North America. HE ended up on an ash filed, with trees beginning to appear around him. Behind him and his jeep is a volcano.

"One day, this area will become some place in Montana, Wyoming, or the Dakota's, but for now, it's a world lost to time."

With the clock ticking, any camp will be temporary, even for a time traveler.

Nigel arrives at his camp. Already, his crew has woken up (what, you thought they just made the camp?) and are preparing for the search.

"Alright, so we know T. rex hunted big animals, and right here, in these ash fields, there isn't a lot of food for large animals, so we need to look somewhere else. There's a forest nearby, so we should start there."

Before he sets off to find T. rex, though, Nigel has one last thing to do.

Nigel sets down his backpack and opens it up. He quickly removes a small set of cages stored within and places them around the camp.

"We may be after T. rex, but nothing alive right now is going to be around much longer, so we might as well save every creature we can."

Once the cages are set, Nigel sets of toward the forest.

It's been a couple hours now. Nigel has yet to find a T. rex, or any other dinosaur, for that matter.

"Well, we haven't had any luck yet, but this isn't surprising. Animals would last very long if they were easy to spot, unless they're poisonous."

Fortunately, Nigel's luck is about to turn around.

Suddenly, Nigel notices something a few meters ahead. It is a trail of footprints. Big footprints.

"Speak of the devil... looks like our luck is turning up. These footprints here, their big enough to fit three of my feet in one of them. There's no doubt, these are T. rex feet; hadrosaurs feet would be more rounded and there are no other big theropods in North America. Now, if we follow these tracks, they'll hopefully lead us to a T. rex.

While Nigel's luck is turning up, he has to be careful. Out here, he's not the only one looking for dinosaurs.

As Nigel's crew leaves, a large shadow falls over the footprint they had been observing. It snarls, before a large clawed foot comes down. It looks like a rex foot, but it's a lot smaller.

And, of course, there's the large sickle claw on it.

Nigel's trek leads him further into the forest. So far, though, the footprints haven't lead to any dinosaurs.

It looks like the footprints were not the good omen Nigel was looking for.

Then, Nigel hears a loud snap.

But looks can be deceiving.

Nigel quickly identifies the source of the snap as a large bush. He motions for the crew to stop.

"Careful now, there might be a dinosaur nearby. It's too small to be an adult rex, but a juvenile could be hiding in those bushes. They lived different lives than their parents and some have even been mistaken for different species."

Nigel motions for the crew to approach the bush. As they begin to do so, something pops out of the top of the bush.

It's a dinosaur. Or, rather, the head of one. It is blue, with yellow eyes and black pupils. The head has a small feathery crest on it. It looks down at Nigel, then screeches. LOUDLY.

Needless to say, Nigel is a little surprised.

"Whoa! Well, what do we have here?"

Nigel looks at the head for a moment, which then decides it has had enough with Nigel. The dinosaur emerges from the bush, revealing its plumed body. The are mottled grey feathers all over its body, except its arms, which are clawed, feathery wings. It quickly begins screeching again at Nigel, who decides it best to cooperate with the angry dinosaur and retreats to cover behind a tree.

"This is both exciting and scary for me. This dinosaur, it's an Ornithomimus. They're members of the Ornithomimosaurs, the ostrich dinosaurs. They're known to live in flocks, so if there is one here-"

The Ornithomimus screeches again. This time, there are several other screeches in reply, and several more heads emerge from nearby bushes. Some are blue, others are grey, but they all look like the first one."

"- then there's more nearby. "

The ostrich dinosaurs look around, confused, for a moment. When they are sure the threat has passed, they begin to resume their activities. Namely feeding. Some remain in the bushes, others move into the open.

Though they are not T. rex, these strange and wonderful creatures will soon join it in extinction.

Unless Nigel can rescue one for Prehistoric Park.

Nigel quickly gets to work. He sets down his backpack, takes off his left shoe, and removes his sock. Additionally, one of his crew takes out a horse lead.

"Now, these aren't T. rexes, but I would love to have an Ornithomimus or five at Prehistoric Park. The problem, though is catching them. These dinosaurs can run as fast as ostriches, who can go at 96.6 kilometers per hour (that's 60 mph, for my fellow Americans). So, I'm going to try an old trick. I you put a cover of any sort on the head of an ostrich, it will calm down, so I am going to see if that will work on these dinosaurs."

Nigel quickly puts his plan into action. He approaches the flock of theropods slowly, looking for on to catch. Once he finds his target, he charges. They flock scatters, but Nigel is able to tackle on to the ground. With difficulty, Nigel is able to force his sock over the dinosaur's head, then attach the lead to its neck.

As he does so, however, he doesn't notice that the Ornithomimus flock has returned. At least, not until they start running past him. As he tries to dodge the panicked theropods, he feels the ground shake.

He looks up... and finds himself face to face with a pack of T. rex.

It looks like the T. rex have found Nigel before Nigel could find them.

The rexes stare at Nigel. They're curious, they haven't seen anything like him before.

Nigel takes his chance and flees with his Ornithomimus. The rexes quickly follow, for if something this small is running from them, it must be prey.

Nigel needs to lose the rexes very soon. Even though it isn't as fast as the movies show, a Tyrannosaurus is still faster than a human could ever be.

Nigel, his crew, and their first catch move into a thick set of bushes. The rexes, despite their hunger, are reluctant to follow.

Nigel does have one advantage here. T. rex is so top heavy that a fall could kill it. And Nigel isn't worth that risk.

Nigel and his crew reach the end of the underbrush. Against the odds, they are still alive, and still have their dinosaur.

"Well, that was close. Those T. rexes, I won't lie, they are the scariest things I have ever seen. Well, we found them, but I think we need a new strategy for catching them."

Just then, Nigel hears a snap from right behind him. He turns around... and finds himself face to face with another Ornithomimus.

"Well, what do you know. We have another Ornithomimus. Wait, I recognize this one. It's the very first one we saw. It must have fled into the undergrowth when the rexes came."

The Ornithomimus continues to stare at Nigel, then screeches again. This time, tough, Nigel isn't backing down.

"Come on now, let's go catch ourselves another dinosaur.

A short scuffle later, and Nigel now has two Ornithomimus.

"Well, I think we should head back to camp. It's getting late and I don't want to hunt a rex at night; they'll see us well before we see them."

As Nigel gets ready to leave, there is another snap. It's softer, though, and is followed by several more. The source is a small clump of bushes.

As Nigel gets ready for the new creature, out of the bushes comes a small dinosaur. It's covered in feathers and is brownish red, with wings, just like the Ornithomimus. What sets it apart, however, is its small size, its sharp teeth...

And its decently sized toe claw.

"This is amazing. This little guy, he's an Acheroraptor. This was one of the last of the raptor dinosaurs, and was one of only two that lived with T. rex."

Just then, another raptor merges from the bushes, followed by a third, then a fourth, a fifth and, finally, a sixth. All of them are staring at the crew.

Now, normally, a pack of raptors staring at you would be worrisome. For Nigel, though, this is an opportunity not to be missed.

Nigel gesture for his crew to take the two Ornithomimus, then give him a tarp, with two men assisting him.

The raptors begin to bark at the crew, trying to scare them off. Nigel, however, refuses to back down.

Nigel and his crewmen charge, completely surprising the raptors, allowing them to tackle all of them to the ground. As the raptors struggle to escape, several other crew men get out dog carriers to put the raptors inside.

"Well, that was exciting. I guess we're the first people to ever fight a raptor. First to win, too. Come on, then. Let's get back to camp.

Nigel may not have a T. rex, but a pack of raptors and a pair of Ornithomimus is a good start.

By the time Nigel gets back to camp, it is already dusk. The sun has begun to set, and the creatures of the night have begun to stir.

For Nigel, its time to check the capture cages. He quickly secures the ties the Ornithomimus to some nearby trees, secures the raptor cages, then starts opening the cages.

Here, Nigel is much luckier than he was in his search for the T. rex.

Inside the first cage is an odd creature: It looks like a salamander, but it still has gills and only has its front pair of legs.

"This little fella, he's called Habrosaurus. He's one of the sirens, special salamanders that never lose their gills and only grow two legs. These guys are still around today, which is pretty surprising. You see, amphibians like this guy are extremely sensitive to changes in the ecosystem, so when the meteor hits and fills the air with toxic chemicals, these guys should be dying out en masse, yet their descendants are still around today. I think that, for these creatures, survival ultimately came down to luck."

Nigel quickly puts the siren into a better storage place, then adds continues examining the cages. Within them he finds lizards, insects, the odd turtle, even a few birds. The last ones, though, offer a more interesting set of creatures.

The last eight cages each contain a mammal, but all of them are under assault be a variety of larger creatures. One pair is being attacked by a pair of creatures that appear to be a cross between a gila monster and a komodo dragon, another pair are under siege by two giant snakes, a third pair is being harassed by two gharials, and the final pair is under assault from a pair of giant turtles.

"Well, this is interesting. The mammals in those cages are Cimexomys, Cimolodon, Cimolomys and Essonodon. They are members of the multituberculates, the only great group of mammals to ever go extinct. As for their assailents, the lizards are Paleosaniwa, the snakes are Dinilysia, the gharials are Thoracosuchus, and the turtles are Basilemys. These predators must have seen the mammals get trapped within the cages and decided to try and get an easy meal. Fortunately, we planned for this and made the cages strong enough to be used as car jacks, and we also brought bigger cages for these guys."

Nigel quickly gets out the larger cages, then fill them with heavily scented bait. The predators notice this, change focus, and are swiftly caught.

Nigel proceeds to secure the mammals, then gets ready to go to sleep.

Nigel may have got off to a good start, but he is racing against time here. If he wants to get a T. rex, he'll need to step up his game.

The next day, Nigel wakes up to some new neighbors.

Nigel is busy washing his face, until he looks up... and finds himself face to face with a herd of horned dinosaurs.

More titans in the last days of their reign.

"Wow, this is amazing. These dinosaurs, they're ceratopsians. The most famous one is Triceratops horridus, and they certainly make up a good part of this herd, but I can also make out Triceratops prorsus, Torosaurus latus and Tatankoceratops sacrisonorum. I can also make out some Leptoceratops in the herd as well, and some Pachycephalosaurs. They're Pachycephalosaurus, Stygimoloch, Dracorex and Sphaerotholus. All these dinosaurs enjoyed widespread success during the cretaceous, but ultimately, it didn't save them."

"Seeing these animals is a good thing, because they are big prey animals, and wherever there are big prey animals, there are big predators. I saw a track way a little further up, so I'm going to follow it and see if I can find a T. rex.

A few hours later...

Nigel is still following the footprints. This time, he's having a little more luck. The tracks have led him to a set of rocky crags within an ash field. And here, there is a lot of Tyrannosaur sign.

"There's T. rex footprints all over the ground here, from animals of different ages, sizes and genders. Scientists believed that Tyrannosaurs lived in packs and so far, what I've seen proves it. That doesn't mean that everything that went on in these packs was civil, though. Scientists have found T. rex bones with bite marks from other Tyrannosaurs on them, and there are a bunch of drag marks here, which probably came from Tyrannosaurs throwing each other around. These marks aren't big enough to be full grown rexes, so it was probably the juveniles doing the fighting. Still, all of this is a good sign for us, it mean that we're approaching the center of their territory and can't be far from them now."

What Nigel doesn't know is that he's already at the center of their territory and that the T. rexes are right around the corner.

Nigel climbs over a hill to find himself staring at a pack of T. rex. Fortunately for the exposed human, the pack doesn't notice him, as most of the animals are busy either fighting each other or looking at bones for any extra meat they can find. Small mammals also search the bones for food; they can do so with impunity, as they are too small to be a good meal for the Tyrannosaurs. To the far right of the group lies an odd mound in the ground.

Nigel quickly takes cover behind a rock, then starts examining the Tyrannosaurs. For a zoologist, this is a golden opportunity.

More importantly, it's also a chance to end his mission here and now. If Nigel can lure one or two of the rexes away from the main pack, he will have an easier time getting them into the time portal.

"This is amazing. These rexes, they have interesting pack dynamics. The sub adults, they're fighting amongst each other for dominance, while the adults just don't seem to care at all."

While this is a golden opportunity for Nigel to observe the rexes family behavior, he may have lost his chance to end this mission here and now.

One of the rexes bellows at the others, signifying something. The rest stop what they are doing, then follow her.

"That female, she's just called out to the rest of them, and they listen. Modern evidence indicates that Tyrannosaur packs were like wolves: the alpha's were the parents., while the rest of animals were their children. I think that female was the alpha, and the rest are either her children or her mates."

While Nigel may have lost the chance to bring back a fully grown tyrannosaur, he now has the chance to explore their den for something far easier to take back home: eggs.

"All dinosaurs, no matter how big they grew up to be, came from eggs that I could easily fit inside my backpack. Now, that mound on the edge of this area, it has to be a nest; no other creature would want to live next to T. rex for any reason at all."

Nigel approaches the nest, sets down and opens his pack, then starts digging. After a short amount of time digging, he pulls out an egg. Unfortunately for him, its broken.

"Well, this is what I was dreading. It's an egg, but it's obviously not fresh. It might have been eaten by a predator, but since there is only one small hole in it, it's more likely it was from last season's clutch."

There goes Nigel's chance to end the mission now.

"Well, we should probably head back to camp now, it's a long trek back."

Nigel gets up, get's his pack, then gets ready to leave.

"I could have sworn this was lighter when I put it down."

As Nigel is about to leave, though, he notices something.

Amid the bones of a Triceratops, there are three small dinosaurs. They're raptors, but they are slenderer than the Acheroraptor he caught earlier. One mottled brown and yellow, another is black and purple, while the third is mostly green, with red arms and wings.

"Well, this is interesting. Those are troodontids. They're the smartest of the non-avian dinosaurs, and ,by the looks of it, we've got two species here. Two of them, the brown one and the black one, those are Pectinodon, while the last one, its a Troodon. They must have been waiting for the rexes to leave, then come in to search for food. The meat on the carcass might have been what attracted them, but they might be after the mammals that were hiding in the bones."

Just like with the Acheroraptors, this is an excellent chance for Nigel to get new residents for the park. This time, though, he's going to take a less aggressive approach.

Nigel removes his pack and pulls out a piece of meat, then holds it up toward the troodontids. The Troodon is the first to notice and walks right up to Nigel, who throw the meat down in front of it. It sniffs the meat for a moment, then digs in. Soon the Pectinodon notice, and stare intently at Nigel. He repeats his trick and soon has two more dinosaurs eating in front of him. After the raptors finish eating, the troodontids begin to follow Nigel.

"Well, looks like I'm now an honorary troodontid."

Halfway between the rex nest and his camp, Nigel comes across a beach, off all things.

"This is the Western Interior Seaway. The polar ice caps are practically nonexistent at this point, so sea levels are much higher now than they are today. In the oceans, there are giant reptiles, such as mosasaurs and plesiosaurs eating fish, ammonites and each other. Bob has already finished building an aquarium for small marine creature and underwater pens for bigger ones, but while we've set up fish traps in the river to get aquarium residents, I doubt we'll be using the pens anytime soon."

With one last glance at the sea, Nigel resumes his trek to camp.

Unknown to Nigel, far behind him is the silhouette of a large predator. It stares for only a moment, then runs off.

By the time Nigel returns to camp, it is once again dusk.

On the other side of the river, new creatures have joined the ones he saw this morning. Two types of armored dinosaurs have shown up, as well as small two legged plant eaters and much larger ones.

"It looks like we have more neighbors. The armored dinosaurs, they're Ankylosaurus and Denversaurus, the small herbivores are Thescelosaurus, and the biggest new comers are Edmontosaurus. With all of these dinosaurs here, it looks like we have just about every known herbivore from Hell Creek here."

Then, Nigel notices several odd dinosaurs by the trees. They have long necks, stand on two legs and have HUGE claws.

"I don't believe it. Those are Therizinosaurs. They're aren't known from this time in this part of North America, but the fossil record is full of holes, so it looks like we've found a new species. I remember seeing their cousins, Therizinosaurus when I did the Chased by Dinosaurs series, but you never get over seeing such strange creatures."

For Nigel, they are a wonderful sight to see before going to sleep. Still, he's now gone two days without a T. rex. Now, the first signs of trouble are showing. The sky is filled wit shooting stars. These meteors are merely precursors to the asteroid that will end this era in in the Earth's history.

"Look at all of this astrological activity. These meteorites, they aren't a problem, they'll burn up in the atmosphere long before they hit the Earth. The real danger here, though, is what follows. These meteorites are precursors to an asteroid the size of Mount Everest. Once it hits, well, let's hope we're not here when that happens."

The next day, the T. rex pack turns up to stir up trouble.

The Tyrannosaurs have arrived. They are on the opposite side of the river from the plant eaters, and they're hungry.

They're here because, for them, it's an all you can eat buffet.

The herbivores all notice the rexes. Some seem ready to run, others prepare to stand and fight.

The stalemate doesn't last long. The rexes charge into the massive herd, searching for a good meal.

Few animals here are defenseless. The ceratopsians have their horns, the ankylosaurs their armor, the therizinosaurs their claws and the hadrosaurs their bulk.

For the smaller animals, though, running is a good option.

The herd rapidly breaks apart. Smaller dinosaurs run toward a nearby forest, juveniles of the larger animals head into water, spooking some crocodiles in the process, while the adult hadrosaurs, ceratopsians, therizinosaurs and ankylosaurs stand their ground and try to intimidate their foes away.

In the ensuing chaos, Nigel is clipped by a turning Triceratops. Fortunately, all he receives is some whiplash.

"Feels like a speeding train."

Back in the middle of the chaos, one Triceratops runs into the worst place possible: right in front of the female rex. The young animal soon finds itself caught in the rex's jaws. The more it struggles, the deeper the rex's teeth dig into its flesh.

Fortunately, help is on the way. A bull Triceratops charges the rex and gores her through the left leg, forcing her to release her quarry. She tries to bring down the male, but he refuses to give up without a fight.

The male rexes, seeing that the hunt is a lost cause, turn tail and run.

So much for hunting in a pack. Now the female rex has to make a kill on her own. And she looks like she's found her target.

Amid a small group of plants near Nigel are a group of dinosaurs. The most prominent is a nearly fully grown Triceratops, but adolescents of all the large herbivores hide with it, along with members of all of the smaller dinosaurs, some mammals, and a few birds. Hiding might have helped them before, but now, they are defenseless.

For Nigel, it's the chance he's been waiting for.

Nigel activates the portal. His crew begin gather all of the animals they've caught, including the water tanks for the aquatic residents. Oddly, in some of the cages are large flightless birds.

"Alright, so, maybe we can get all of these dinosaurs into the present together. If I can get this Triceratops through the portal, the rest of the dinosaurs may follow it, and the rex will follow them through."

Nigel takes off his vest, then uses it to try and get the Triceratops to follow him. As the rex gets closer, the Triceratops finally relents and heads toward Nigel. The rest of the plant eaters, along with Nigel's other catches, quickly follow through.

The rex, however, refuses to take the bait.

In the present, head keep Bob is crossing the walkway above the portal just as the motley herd Nigel saved bolts through.

"Well, those certainly aren't T. rex."

While that may be true, at well over 40 tons of plant eaters, it's a great start for the park.

While the rest of the keepers get to work feeding the new guests, Bob has a chat with Nigel.

"What all did you bring back?"

"Let's see: there's the ceratopsians Triceratops horridus, Triceratops prorsus, Torosaurus, Leptoceratops and Tatankaceratops; the hadrosaur Edmontosaurs; theornithopod Thescelosaurus; the ankylosaurs Ankylosaurus and Denversaurus; the dromaeosaur Acheroraptor; the troodontids Troodon and Pectinodon; the pachycephalosaurs Pachycephalosaurus, Stygimoloch, Dracorex, and Sphaerotholus; and, lastly, some therizinosaurs. This one's an undiscored species, so I guess we get to name it. Oh, and we have two Ornithomimus and a bunch of smaller animals too."

"Well, you certainly brought back a lot of animals."

"I know. Before I got back, I think I need to find a place to put all of them."

Back at his den, Nigel is doing just that.

"Now, all of these dinosaurs lived together, so I can group the nearby each other. Now, these guys lived nearby streams, plains and forest, so I think I know exactly where I want to put them."

Already, Nigel has put the new exhibits on his map. One stands out in particular: Triceratops Creek.

At Triceratops Creek, the staff are about to unload the newest resident: the male Triceratops. As soon as they have the truck carrying him in his exhibit, he's free. He's soon joined by seven other Triceratops. Six of them are Triceratops prorsus, while the last one is a young female Triceratops horridus. She's the one the female rex was trying to eat.

"I think I'll call our first dinosaur Theo. It just suits him. Now, the thing with dinosaurs is that grass didn't show up until the end of the Cretaceous, and it was confined to India at that time, so we had to fill his exhibit with ferns and bushes, 'cause w aren't sure how his stomach will react to grass."

In order to reach his maximum size of nine tons, he'll have to spend most of his life eating

While everyone else is busy acclimating the new comers, Nigel is heading back to the Cretaceous. he still has a T. rex to catch.

He soon finds a set of footprints to follow, and there's only one animal this can belong to.

"These tracks here, they're rex tracks. These ones are different, though. There's drag marks between every left footprint. I think these are from the female we saw earlier. Her leg was gored by the Triceratops, so she has a limp, which could explain the drag marks."

Nigel quickly finds out how right he is. Ahead of him is the she-rex. She's staring intently at the river, for some reason.

"There's the female. She's looking at the river. There's something in there...it's a Triceratops. It must have drowned when it ran into the water. The rex, she really want to sink her teeth into that carcass, but she doesn't want to go into the river to get it. The river's running so fast that there's a major risk of the rex getting tipped over."

The female eventually leaves, realizing that she won't find a meal here.

Nigel follows her, but she ultimately outpaces him. He then decides to follow the river, on the off chance the mother is merely headed down stream.

The river ends up taking him to the beach he was at earlier. This time, though, it isn't empty.

On the beach are eight large reptiles. Two are seal-like, but with crocodilian snouts and fluked tales. Another pair are huge sea lizards, while the third pair resemble shell-less turtles, except for their GIANT necks. The last two also resemble crocodiles, but with longer legs and pronounced sails on their backs.

"Well, this is new. Those giant lizards are mosasaurs, the long necked ones are plesiosaurs, but the seal creatures. I don't know what they are. The sail backed ones look like spinosaurs."

While they may be strange, these creatures are in big trouble: they're so heavy that they can't breath on land.

If this were a normal day, these creatures would soon be dead. Fortunately for them, Nigel is here.

Nigel sets up the time portal, but has a new plan. He first coaxes the seal-like animals through the portal with fish, as unlike their larger competitors, they can still move on land. They are soon followed by the they are through, he grabs one of the portal sticks, while one of his crew grabs the other, then walks forward. This lets him get the mosasaurs and the plesiosaurs through without having to lift them, which would be a problem with such large creatures.

In the present, Bob is at the underwater holding pens. And not a moment to soon. After the strange seal like animals come through, the giants of the oceans soon follow them. Bob quickly puts them in separate pens, the mosasaurs might eat the other creatures if they're hungry.

"Well, I wasn't expecting to use the marine pens today. I wonder if he'll give me any sea birds. Those weird flightless birds he brought back, they're Brodavis, essentially Cretaceous freshwater penguins. Nigel's met they're marine cousins, Hesperornis, before, so I wouldn't be surprised if he brought some back with him."

Back in the Cretaceous, Nigel is changing his plans up a bit.

"We've figured out that the female rex is coming down this way, so we're going to try a new strategy. There's a lake on one side of us, and we're using logs to build a wall on the other side, so that, when she comes down here, she'll be funneled into the portal.

Nigel's plan better work, he's running out of time very quickly now.

Meanwhile, in the present, the staff are having a problem with one of the new residents. It's Theo.

The Triceratops is rubbing his head against a tree for some reason. Bob may be the head keeper, but this problem is outside of his area of expertise, so he's calling for help.

That help is quick to arrive. It's Susan McNab, the park's head veterinarian.

"So, what's wrong with Theo?"

"He's been rubbing his head against that tree for half an hour now. I can't tell what's making him do that."

As the two heads of staff look at the Triceratops with worry, Susan notices something new.

"Look at his crest."

"Why?"

"It's changed color, it's a lot brighter now."

As Bob examines Theo's change in attire, Susan figures out the problem they are dealing with.

"I think Theo is ready to breed. He might be having a huge surge of testosterone and mistaking the tree for a rival."

Upon hearing this, Bob has an idea. Susan notices this,

"Why are you smiling?"

"Oh, nothing, I just had an idea."

"Oh, no, what is it?"

"Wait and you'll see."

While Bob gets to work with a solution for Theo's hormone problems, Nigel is having unexpected guests.

In front of Nigel are two dinosaurs. Two large, long necked, armored dinosaurs.

"This is amazing. Those dinosaurs, they're Alamosaurus. The were thought to be restricted to the southern parts of North America, but this proves us wrong."

Nigel can't believe his luck, but unfortunately for him, it's about to change.

Suddenly, Nigel here's a screeching noise. He looks to a nearby hill, where he can now see two large raptors.

"Oh dear, those are Dakotaraptor, the biggest raptors in North America at this time. They aren't a threat to the sauropods, but we're a different story."

Nigel soon finds out that he's right: the raptors are charging toward him.

Before they can get very close, though, six large shapes descend from the sky. Once they land, they begin harassing the raptors.

"Those are Quetzalcoatlus, the biggest pterosaur ever. These are land predators, and either they want to eat the Dakotaraptor, or they want to eat us and don't want to share. Also, I think there's another type of pterosaur there, but I can't determine the genus."

Before anyone can get injured though, a loud roar cuts the standoff to a close.

The T. rex has finally arrived, and sandwiched between her and the portal are a group of Ornithomimus, another ornithomimosaur, and two types of crested dinosaur.

Nigel is quick to activate the portal. The sauropods, raptors and azhdarchids run through the portal, driven on by fear of the giant killer. They are soon joined by the flock of dinosaurs in front of the T. rex.

In the present, Bob is dealing with the new comers.

Bob can only stare at the Sauropods as they come through, having several near misses with the smaller creatures.

Back in the Cretaceous, one Ornithomimus is too slow to reach the portal.

A young Ornithomimus is chomped down on by the female rex, who demolishes the wall in the process. She quickly turns around and carries it away with her. Nigel is quick to follow.

In the park, Bob has finally gotten all of the new residents settled in.

The Alamosaurus have been moved into a grove of their own, while the crested dinosaurs (who turned out to be Anzu and Leptorhynchos) have settled into their new exhibit just fine. As for the Ornithomimosaurs, which were Ornithomimus and Struthiomimus, Bob moved them in with the pair Nigel had already saved. The raptors were given a well shaded exhibit to hide away in.

"I'm not gonna feed the Ornithomimus and Struthiomimus 'til tomorrow, that way, they can get some time to settle in.

With all of that settled, Bob can finally focus on his pet project. What it is, however, remains to be seen.

Back in the Cretaceous, Nigel is still following the female. She's going so slow now that he can easily keep pace with her.

"I don't know why she hasn't eaten her kill yet, she must be starving now."

Finally, she reaches a little den within a rocky crag. Here, Nigel gets his answer.

Emerging from the crag are two juvenile tyrannosaurs .They are quick to approach the female, who offers them the Ornithomimus. Hiding in the nearby crags are small, furry mammals and little chicken like dinosaurs, eager to try to steal the scraps.

"It's been a long climb, but it's worth it. There are babies here. That's why the mother brought the carcass here, even though she's badly hurt: the babies need food. For a long time, paleontologists have suspected that dinosaurs showed parental care, and for us, this is just wonderful, we can bring back a T. rex family."

Nigel's optimism is about to be short lived, though.

Another T. rex shows up. This one is a male, and he's hungry.

The mother turns to face her opponent, while the babies hide. If the male finds them, they'll be in trouble. Like all predators, Tyrannosaurs were probably cannibalistic.

The male and female fight, until the female grabs onto the male's neck. As he struggles to break free, he accidentally smashes the mother's head against the walls of the crag, critically injuring her. She quickly goes down.

The male, having won the battle, claims his meal.

As he leaves, Nigel approaches the mother. Even in her extreme state of injury, she's still alive.

As he wonders what to do, he hears another roar behind him. Another male rex has arrived. And this one can see the babies. Strangely, though, he seems more focused on the female.

As Nigel wonders what's going on, the whole world suddenly glows very brightly. In the distance, a great ball of light has appeared.

The meteor has finally arrived.

The asteroid crashes into the ground, releasing an enormous bang as it does so. Nigel is forced to look away and cover his ears, but he is still affected by the light and sound.

The asteroid strikes with a force that is several billion times that of the Hiroshima Bomb. It releases a blast cloud that travels at over 1,000 times the speed of sound. Additionally, it sends flaming debris into the sky that will soon rain back to earth. Global earthquakes, volcanoes and tsunamis will follow immediately after the impact. And that is just the start. Acid rain fall will occur from all of the pollutants throw into the air, and the entire world will be covered in darkness from the ash cloud that will follow.

For Nigel, though, the immediate problem is getting the rexes into the portal.

The male has moved near the female and is trying to raise her up, with a lot of difficulty.

"That male, he must be her mate, which means he must be the father of the babies. Now, I need to do something, otherwise they will all die."

Nigel quickly gets to work setting up the portal. As he does so, the blast waves grows closer and closer. The male rex is finally able to get his mate back on her feet, but she's still not in good shape.

Nigel finally manages to get the portal started. Quickly, he tries to get the attention of the babies using the only meat he has: a ham sandwich.

"If I can get the babies through the time portal, then there's no way the adults won't follow. They can smell the meat in the sandwich, but they're more likely to try to eat me."

As the blast cloud nears, the babies finally follow Nigel toward the portal, joined by the small chicken like dinosaurs and the mammals. As Nigel approaches, the babies stop, cautious of the portal. The parents are right behind them.

Then, the blast cloud hits.

In the present, Nigel, Bob and Susan are staring at the portal, wondering if the rexes came through.

Their patience is rewarded. The babies soon run through the portal, followed by the chicken dinosaurs, small mammals and their parents.

Against all odds, Nigel finally has a T. rex.

The mammals hide in one of the pens side by side with the chicken dinosaurs, while the rexes go into a pen of their own. Bob quickly drops in three pieces of meat: one for the babies, one for the male, and one for the mother.

"Once we can separate the parents, I'll have Susan treat the mother."

For now, though, Nigel wants to let them rest.

The next day...

Prehistoric Park is at last home to its first dinosaurs. One of them, however, doesn't seem to like it here.

At Triceratops Creek, Nigel and Susan are examining Theo. He stares at them for a moment, then charges. They're lucky to get out of the way.

"And he's been doing this since yesterday?"

"He has. I think it's because he's finally matured and there aren't any other males of his species to spar with."

Nigel and Susan's discussion is interrupted, though, by the unmistakable sound of a tractor engine. Behind them they soon find the source: its Bob, with his completed project.

It's a tractor, but it has been padded with tires and has the front end modified so that it resembles a Triceratops.

"Open the gates!"

Nigel and Susan are quick to oblige. As soon as the gates are open, Bob enters the exit. Nigel's quick to catch a ride.

Bob is busy looking for Theo, but soon gets his answer when the tractor shakes from a blow to the rear. Behind them, they find one very aggressive Triceratops.

"There he is!"

Bob quickly backs up and changes direction until he faces Theo, then charges. Theo replies in kind, and soon, animal and machine are locked in combat.

Bob's idea is not as daft as it seems. It's a tactic game keepers use on rhino. This one, though, has the added benefit of letting all of the boys blow off a little steam.

Susan, watching the boys enjoy themselves, cannot help but laugh.

"Men."

Back at his den, Nigel is looking over some triceratops fossils.

"That was exhausting. I'm winded. Still, that was amazing, but that's what Triceratops do. Fossil skulls have been fund with horn marks in them from when they jousted. We might not have any other Triceratops horridus for him to fight, but the tractor is a worthy opponent. The thing is, I have to let him win, because I don't want to let him get injured, he's just too amazing."

Then, Nigel takes out his pack and unzips it. Inside are six tiny mammals. They all stare intently at Nigel

"And it looks like I brought along some unknown guests. These are Cimolestes. These are the mammals we saw at the re den with all of the bones. They must have smelled the food in my pack and climbed in when I opened it. With all of the other Cretaceous mammals, it looks like we can build an exhibit for the little guys."

The mammals continue to stare, to which Nigel offers them a snack.

Nigel's dream of a park filed with prehistoric creatures is beginning to take shape. The ornithomimids are beginning to acclimate to their new home, Theo has started to calm down, and the T. rex have been moved to their new home.

Nigel, Susan and Bob are just outside of T. rex Hill, the home of the tyrannosaurs. Nigel is taking his chance to examine the exhibit.

"Now, this enclosure's so big, way bigger than I'd need for four tyrannosaurs. I'm not mad, I'm glad actually, but why'd you make it so big, Bob?"

"I thought You'd bring back a huge pack, so I built an exhibit for them and their children."

"Well, that's very thoughtful of you, Bob. Have you seen the babies?"

"Not since I put them in. The parents, they're resting out here, but the babies, they've disappeared off the face of the Earth."

The heads of staff all take the time to examine the exhibit to see if they can find the babies. They're lucky, the young are nearby.

The two juveniles burst out of a nearby grove of plants. While their parents sleep, they've taken to exploring their new home.

"Wow, those little felllers are amazing," says Bob.

"And there so fluffy," remarks Susan. "The adults may have well developed feather, but the juveniles just look like, well, giant baby turkeys."

"So," begins Bob, " have you thought of names for them yet?"

"I have. For the parents, the female will be called Sue, the male will be Stan, the juvenile female, who's bigger and stockier than her brother, will be named Matilda, and I'll call the slender juvenile male Terence."

While the staff leaders discuss their names, the juvenile tyrant lizards play fight with each other, then start running toward the fence.

"You know, for how vicious they are, the look really adorable right now," notes Susan.

But they won't stay that way. In time, Terence and Matilda will grow into seven ton killing machines, just like their parents. Let's hope Prehistoric Park hasn't bit off more than it can chew.

Next time, Nigel goes back to the Ice Age to rescue the wooly mammoth.

Managing the prehistoric creatures Nigel brings back will not be as easy...

...As they thought

Author's Notes:

Alright, I've wanted to do this story for a long time. You see, I loved this show when it first aired on Animal Planet on 2006, and I wished that it would have been continued. So, I'm doing a fan fiction of it.

Oh, and for those who haven't heard of it: Prehistoric Park is a show by Impossible Pictures, the studio that made Walking with Dinosaurs, Walking with Beasts, Walking with Monsters (these three are called the Teilogy of Life), Walking with Cavemen, Chased by Dinosaurs, Sea Minsters, and, most famously, Primeval.

Now, here are some things that I'd like to get out of the way:

1. This series will continue for WAY MORE than six episodes. I already have a general idea of nine episodes after the original series ended, and the first three have already had their fauna determined.
2. I will use a lot of speculative behavior for these animals, because really, it's fun.
3. I will save more animals each episode that is based on the original series then was originally rescued in that episode.
4. I will accept fan submissions for creatures to rescue, but only for the episodes of the original series. This will be explained later.
5. Most episodes will be divided into multiple posts. This one was one big post because I wanted to get everything I wanted in it.
6. I will make a list of creatures rescued at the end of each episode. The one for this episode will be up tomorrow.
7. I will explain the backstory in an omake post.
8. EVERY DINOSAUR WILL HAVE SOME AMOUNT OF FEATHERS ON IT. THANK YOU KULINDADROMEUS.
9. If you want an OC keeper, give a detailed description of them. I will make a separate thread for that.
10. No animal OC's for an animal that hasn't been rescued yet. And yes, this means you can have OC animals.
11. Constructive criticism is appreciated, huge amounts of praise will be basked in (but grow annoying if overdone), and flames are forbidden and, if added anyways, will be ignored.
12. FAN ART IS APPRECIATED, MY ARTISTIC SKILLS ARE AVERAGE IF NOT POOR.
13. If you can figure out the reference I left to Michael Crichton's The Lost World I left in the closing segment (with the baby rexes), good job.
14. I may not be able to update, due to vacations, but I will try to update at least weekly.
15. If you would like to Beta this tory, tell me what I can improve on via pm.

Oh, and I almost forgot
