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 on a safari with a difference as wildlife adventurer Nigel Marvin plunges into Prehistory to rescue creatures on the brink of extinction.

He plans 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 was a very big, busy 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 habitats 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 dinosaur museum.

One day, Nigel plans to bring back breeding populations of prehistoric creatures. For now, though, in the meantime, he only plans to bring back a few of each species, to see how they fare in the present day 21st Century.

And he already knows obviously which one he wants first.

Nigel has come to a stop in front of a skeleton. The meanest and scariest of them all. The king of the dinosaurs.

Tyrannosaurus Rex.

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

"The first animal I want in Prehistoric Park is Tyrannosaurus 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, even one slight, and the park may never be. For Nigel, though, the risk is worth the reward.

It's now or never. Once the time portal has activated, he drives through, and ends up in Montana, which is very different than it is today.

Nigel has arrived in Prehistoric North America. The Late Cretaceous Period, 68 to 66 million years ago.

He ended up on an ash field, 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.

And accomplishing the mission is a must if he wants to bring back the dinosaurs from extinction to give them a new chance at life.

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 that the tyrant lizard king, T. rex, hunted big animals, and right here, in these ash fields, there isn't a lot of food for large herbivorous and carnivorous 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 the T. rex, but nothing alive right now is going to be around much longer, as the asteroid isn't very far away, time is running out, 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, they're big enough to fit three of my feet in one of them.

There's no doubt, unfortunately, that these are T. rex feet; hadrosaur 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 yet at the moment.

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

Then, Nigel later hears a loud snap.

But looks can be very 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. Very 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 ostrich-looking 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-looking 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 the T. rex, these strange and wonderful creatures will soon join the king of the dinosaurs in extinction.

Unless Nigel can rescue at least one of them 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 actually T. rexes, but I would love to have an Ornithomimus or five of them 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 before it thrashes and panics, it will calm down eventually, 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.

The entire flock scatters, but Nigel is able to tackle at least one of them, to the ground. With difficulty, Nigel, eventually, is able to force his sock over the dinosaur's head, then attach the lead to its neck. To calm it down.

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 turns to look as the flock of Ornithomimus run away in terror as the ground began to vibrate again. And again. And hearing a loud roar nearby.

He knew what that meant. A giant monstrous predator of the North American Cretaceous Period is approaching his way.

He looks up... and finds himself face to face with a pack of about 3 huge and possibly dangerous, T. rex.

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

The massive Tyrannosaurus rexes stare at Nigel. They're very 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. They make a run for it.

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

Nigel, and his crew, along with 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 trying to bite Nigel, isn't worth that risk.

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

"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. T-Rex has incredible depth perception, their vision is up to 13 times better than a human's."

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 it's small size, its sharp teeth...

And its decently sized toe claw.

"This is amazing. This little guy that walked out of the bush, he's an Acheroraptor. -

This was one of the last of the raptor dromeosaurid 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. And barking at them.

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

Nigel gesture for his crew to take the two Ornithomimus, then they head over and give him a tarp, with two men assisting him in covering them to prepare bringing them back to the present.

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

Nigel and his crewmen charge, completely surprising the raptors, catching them off guard, and allowing them to tackle all of them to the ground.

As the raptors bark and growl, desperately struggle to escape, several other crew men get out dog carriers to put the raptors inside, trapping them.

"Well, that was exciting, luckily. 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. And prepare for tomorrow and try again."

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

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 it's front pair of legs.

>

Still, he's now gone two days without a T. rex. Now, the first signs of trouble are showing.

The sky is filled with 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. Searching for their favorite food. Triceratops.

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 female rex, goring her through her 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 and opportunity 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 maybe, the T-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 female Tyrannosaurus rex, however, refuses to take the bait.

In the present, headkeeper Bob is crossing the walkway above the portal just as the motley herd Nigel saved, started to dash their way 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 porosus, Torosaurus,

Leptoceratops and Tatankaceratops; the hadrosaurs:

Edmontosaurus; the ornithopod 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 in 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 of the enclosures stands out in particular: Triceratops Creek.
