There is something missing from our world: the amazing animals 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.

This time Nigel travels back 150million years to prehistoric Colorado to rescue some of the giant sauropods of the late Jurassic.

Welcome to the ultimate wildlife sanctuary.

Welcome to Prehistoric Park!

Chapter 1- Kingdom of Giants

Wildlife adventurer Nigel Marvin opened a gate that led into the Neanderthal village nestled quietly in the mountains overlooking the park. It was a steep trek but worth it if you wanted to get fit quickly. The village comprised of neat houses that could house at least a whole family. Some of the Neanderthals under the age of five played a form of tag as their parents watched the sun rise early in the sky. Some of the young adults wore modern day clothing, (they preferred the different materials compared to their animal skin clothes), but the older ones chose to still wear their Ice Age clothing. The tribe leader Yoren waved happily at Nigel.

Nigel saved the tribe of Neanderthals some the constant icy winds of winter and built accommodation for them out of the way of prying eyes.

"Nigel you have come to see us at the right time!" he greeted "My son has just returned from the school with the qualifications he wanted!"

"That's brilliant! I've come to drop that book on Prehistoric Life off for you."

"Thanks."

The children and teenagers of the village could go to boarding schools in Switzerland if they desired it and Yoren's eldest had been pursuing a few qualifications. Luckily Neanderthals adapted quickly to modern day life due to their changing world in the Ice Age world. Nigel smiled and he set off back to the park with a few Neanderthals who wanted to work with the animals.

"Hello there," Nigel said to the camera "A deep part of Neanderthal religion is caring for the land, similar to many religions today, so they thought working for the park would be an excellent idea although they like wearing a mixture of modern day and Ice Age clothing."

"I still dislike the Tyrannosaurs though," Yoren's eldest daughter Chia said "The herbivores are fine and the smaller carnivores. A reptile shouldn't be that big."

As the Neanderthals visited their favourite enclosures Nigel went to find Bob and Susan. They were outside the newly extended Smilodon exhibit where the two adults and two juveniles lounged in the sun. They waved at him when they saw him.

"A lot has happened since last time. The Protoceratops eggs have hatched, we've found out the Titanis were actually Phorusrhacos and we've perfected the Neanderthal village. We've installed all modern day amenities they need and more."

"Hello Nigel," Susan said "What brings you down here?"

"Well I hoped Bob could build a large enclosure for some famous dinosaurs."

"What are they?" Bob asked exasperatedly. Nigel pulled out some photos. They were of skeletons of long necked dinosaurs of million years past called sauropods.

"Already we have some Borealosaurus but these sauropods were the most famous: Apatosaurus, Brachiosaurus and Diplodocus. They were all found in the Morrison Formation in Colorado."

"I'll do like I did with our big fellas that we have already."

To catch the sauropods Nigel has to travel back 150million years to Colorado but he had to be wary. Giant sauropods weren't the only giant animals in Colorado.

The ground was bare due to the lack of grass but it was still full of plant life. Nigel had emerged in a giant field of green ferns that grew ankle height. Behind him there was a forest of conifers and pines and monkey puzzles, many modern day plant groups had not evolved yet. Small pterosaurs the size of his hand fluttered in the sky. The sun beat down on them in the cloudless sky.

"This forest would be a good place to camp. Although out sauropods won't be found in there the larger carnivores of the time such as Allosaurus won't be able to either."

They settled in the forest where the jaws of any hungry carnivores won't be able to attempt to eat any of the crew. Anxious to find some of the giant sauropods Nigel set off to find them near the edges of the forest with multiple crew members. They walked in the shade of the huge trees that blocked them from the constant rays of the sun. It did not take long however to find some giant dinosaurs although they weren't the gigantic size of the sauropods Nigel wanted to rescue. Around a small water source there were around four adults and one young one. The adults were 4m high and 9m long but had giant plates arranged on their backs.

"Stegosaurus! I've always wanted to bring these back to the park. Look at those giant plates on the back. As they are warm blooded they can rush blood into those plates for messages such as greetings and warnings and just look at those spikes."

Around the feet of the stegosauruses were ten small dinosaurs pecking at the ground. There were two species next to the stegosaurus; both were three quarters of a human's height and two metres long. One was dark green with even darker green spots while the other species were light green with white stripes and a blue head. They were types of hypsilophodontid.

"The green hypsilophodontid is named Dryosaurus while the blue headed one is named Othnielosaurus. They rely on speed to escape predaotrs but also stay close to larger herbivores like these stegosauruses. I'm tempted to bring them back to the park for Bob to look after. His favourite dinosaur is stegosaurus."

Nigel grabbed some ferns and devised a plan using the small brain of the stegosaurs. He set up the time portal and got the crew to collect some more ferns.

"These ferns will lure the stegosaurus to the portal and because our little dinosaurs rely on our larger ones for safety they will happily follow them through to the safety of the present."

Luckily the stegosaurus agreed with the plan and found the ferns very appetising. With mammals being largely alien to them they weren't scared by the crews scent. Quickly the herd were through the portal with the ten hypsilohodontids following after.

Back at Prehistoric Park Bob has just finished building the exhibit for the giant sauropods that Nigel plans to save.

Bob stood on a platform overlooking a large metal fence that stretched through trees and a field of ferns. A nice large lake sparkled in the sun like diamonds. Bob looked happily.

"To stop our Borealosaurus from escaping we built these fences to stop them terrorising all the park residents."

Once the Borealosaurus stampeded and broke into multiple exhibits causing a mass breakout, including Matilda's.

The radio at Bob's waist whirred into life and Susan's voice came from it: "Nigel's brought back some creatures that aren't the sauropods."

"Good grief!" Bob sighed.

"It's some stegosauruses," Then Bob smiled.

In Prehistoric Colorado Nigel is still looking for some of his sauropods but he might have struck the jackpot.

Nigel was sitting on a large boulder looking at the sauropds. Two species grazed on trees in a clearing, the taller species eating the taller leaves on the trees. The taller were a grey with a green back and had a long vertical neck. The smaller was a light green with a dark green back but had a small head.

"The taller species is the one I want, the Brachiosaurus. The shorter is another species named Camarasaurus. They are both sauropods and are just massive. Maybe we can catch both species using my master plan."

Crew members opened their backpacks revealing masses of small rocks and pebbles.

"Sauropods have been found with small pebbles in their stomachs. This was done to help them digest their food as it speeds up the process. Hopefully they'll be tempted to have some of our stones to digest this foliage here."

It took a while to attract the attention of the tall dinosaurs. They looked down upon the gravel and followed the crew's packs for the devices to quicken their digestion. The two giant dinosaur species were then safely through the portal ready for the awe inspiring gasps of the Prehistoric Park staff.

The superkeeper Bob had immediately the dinosaurs transport and they were ushered into the enclosure with the Stegosaurus, Dryosaurus and Othnielosaurus.

The two species were swallowing happily the pebbles supplied by the crew to ease their digestion. One of the Camarasaurus was drinking out of the lake with its long neck in the sun.

"It's like looking at a lost world," Susan gasped.

"I love those Stegosaurus," Bob laughed.

"I know," Susan laughed "You've been feeding one ferns for an hour."

"I better get back off to the Jurassic to save our Diplodocus and Apatosaurus."

Nigel has gone to a different area in hope to find the giant sauropods of the Mesozoic in hope to rescue them for the Park.

The land was more barren than last time he was there. Most of the ferns were shrivelled up while a nearby tree was bare. A river bed had no water flowing through it and the skeleton of a fish stuck out of the dried mud. The ground was cracked from the continuous bombardment of the sun's rays.

"We're in the dry season now so the lands dry as a bone. You might think that we'll find no dinosaurs here but we have a certain advantage. Sauropod footprints have been found migrating in mass during periods of dryness, obviously looking for vegetation and water to survive."

Nigel pulled out a bottle of water and drank from it. Some members of the crew followed suite to quench the dryness of the desert. A few small pterosaurs flew above head east in obvious search of life.

"Footprints have been found migrating in this area from around this time so hopefully we can find one of our sauropods or possibly even both of them."

The crew erected areas for shade to sit under to escape from the sun overhead. The day was relentless and it took hours for any sign of stopping. At the end of the day the horizon glowed orange as the sun started to set and allowed to creep in.

"It looks like our sauropods won't be coming for a while so we might as well rest. With their size we should hear them from a least a couple of miles off."

Although there might be no life in the daylight but the night is cooler allowing some hungry predators to come out for the hunt.

Nigel was shaken awake by one of the Neanderthals. His face was white with fear as he handed Nigel a torch and pointed in a direction. Nigel looked in the direction to see three 18 foot long therapods standing nearby, smelling the crew. They had three horns on their head and were red in colour.

"These are Ceratosaurus. They're found here and in Portugal. I don't know of any way to evade them other than the portal."

Quickly Nigel set up the portal as the carnivores charged. The portal was opened and they disappeared into the 21st century.

"Let's get some sleep."

As Bob finds a suitable area for the Ceratosaurus Nigel wakes to find some giant surprises.

There was a small herd comprising of 24 individuals of two species. One was a long sauropod with a whip like tail and spines running down its back while the other was larger but shorter in length.

"Yes! The longer one is Diplodocus and they use that tail to deter predators while the Apatasaurus there uses its size as a deterrence. Now to open the portal in front of them."

While Nigel set up the portal the sauropods shrieked as five shapes jumped onto the stomach of a young Diplodocus. A jaw snapped on its head and it fell over dead. The attackers were therapods and had long arms ending with claws and two ridges above the eye. In fear the herd stampeded from the predators.

"Allosaurus. They hunt all the Jurassic herbivores. Once I catch these I might watch them."

The stampede helped quicken the sauropod rescue but Nigel hung back to watch the Allosaurs eat. Curiously they only ate the soft body parts.

"Unlike T-Rex they can't crush bone so they only eat the soft parts."

The dinosaurs looked at Nigel and started approaching him. He took it as a sign to leave. Immediately he emerged into the park and was waving at Bob who had just organised the transport for the new arrivals. His eyes then turned from happiness to fear.

"Look out!"

Nigel looked to see five Allosaurs emerging from the portal behind him. Nigel ran from the hunters and escaped through the latch before they realised that they were in the wrong time zone.

After Nigel has recovered from his close encounter with Allosaurs he goes to visit the new Jurassic herbivores.

The sauropods stood in the lake drinking out of it. The smaller but still giant Stegosaurs ambled around happily with the smaller Dryosaurs and Othnielosaurs pecking at the ground for food. A true lost world.

Next time on Prehistoric Park: Nigel travels back the furthest he's ever been to rescue some unusual sea creatures and the young Tyrannosaurs start to cause trouble. All next time on Prehistoric Park.
