***Big Blue Killer Whale*** is the second episode of Series 3 and the twenty ninth episode of *Prehistoric Earth: A Natural History*.

## Synopsis

The team goes back in time to rescue a primitive species of whale. At the same time they rescue many of the large land mammals of the Late Eocene

## Plot

At the park, the team does well bringing back many kinds of prehistoric animals especially since they are starting to rescue mammals. Allen heads to the park's aquarium and watches the Liopleurodon and Tylosaurus and then heads to the whale enclosure to check on Nate, the park's resident Ambulocetus and has an idea of what he will rescue next. Allen goes to Joanna's office and tells her that he is going to rescue a large primitive species of whale called Basilosaurus as he shows her a drawing of the animal's skeleton and tells her that the scientists thought that Basilosaurus was reptilian and even showing her a 1960 drawing of Basilosaurus showing the same reptilian design. However Allen then shows Joanna the photo of Basilosaurus' skull and tells her that the teeth in the front were for seizing prey and were sliced by the whale's back teeth. The team opens the time portal and then arrive in a mangrove swamp on the site where Cairo Egypt will one day be built.

Allen's dog Caine then sniffs some animals as Allen and Rebecca follows them. Caine then sniffs a pile of dung that Allen analyzes that it was made by a herbivorous animal that waddles. They soon found the mystery animal, a large rhinoceros-like mammal related to elephants called Arsinoitherium whom was aware of Allen and Rebecca's presents as it looks at them but can't see them due to the massive horns that is covering it's eyes. Allen approaches the animal, but the Arisinoitherium charges like a rhino at him. He has some of the team members to rescue a few Arsinoitherium and brought to the park where they were put into the hippo enclosure. Once the Arsinoitherium were brought to the park, the team heads further down the mangrove on canoes to find other animals.

As the team travels down the waterways of the mangrove, Rebecca spots a group of primates called Apidium in the tree watch the team passing by. Crystal then spots something in the water which reveals to be a large hippo-like mammal called Moeritherium. The team watches the Apidium crossing the waterway with some of them leaping from trees while some travel across a branch in the water until one of them gets killed by an Eocene shark called Physogaleus*.* The team rescues both the Apidium and a few Moeritherium for the park. Allen swims in the edges of the mangrove where he encounter a smaller species of early whale called Dorudon swimming together as a pod.

He gets both the Dorudon pod and a few Physogaleus back to the park so they would thrive in their enclosures. However the team were soon followed by an Eocene crocodilian called Pristichampus before they captured it and put into the crocodile enclosure with another one they rescued. Having already rescued the animals living in the mangrove, Allen and the team heads out to sea to rescue Basilosaurus. Shaun joins them and brings underwater recording equipment as he believe Basilosaurus can communite much like modern whales. They finally drops anchor so Shaun can try out the equipment and find Basilosaurus as he puts the hydrophone into the water.

However after a few hours of recording they only hear fish and shrimp, so they head to another spot to try again. This time Shaun picks up some eerie noises on the hydrophone, Allen analyzes it as the sounds of a whale and believes that they have finally found Basilosaurus. They record the sounds and plays it on a massive speaker across the ocean to get the whale's attention. Suddenly the boat moved a bit as Caine barks at a large Basilosaurus appears with a splash. Allen and Rebecca puts their scuba suits on and heads into the water where they found a large female Basilosaurus which Rebecca calls her the Big Blue Killer Whale.

The Basilosaurus grabs and bitten the speaker off before it dropped it and draws the attention of a male that mates with her. The team sets up the portal and rescues the two Basilosaurus as they head into the waterway where the portal was set.

Once they get them through the portal, they transport the two whales to the whale enclosure. Later on Allen heads to the Ostrich enclosure to check on the Ornithomimus which one of them finally laid eggs which hatched into the first baby dinosaurs in 65 million years while two other eggs were being incubated in an incubator after the mother rejected them. He then heads to check on the park's first Eocene animals such as Leptictidium and Gastornis where he realizes that when the Late Eocene came and when the climate became cooler and dryer land mammals evolved from small forest dwelling creatures to large vicious, aggressive beasts while large carnivous birds such as Gastornis were replaced by mammal predators. He also knew that on the landscape during the Late Eocene mammals dominate planet much like the dinosaurs did before them.

Allen tells his boss that he is now going to rescue the large land mammals of the Eocene. The team opens the portal and arrive on a beach where they found an Eocene species of Sea Turtle called Puppigerus heading back to the sea after laying eggs. They get a few of them back to the park where they put into the aquarium. Caine then barks at something running on the beach and Allen saw it was a large hoofed mammalian carnivore called Andrewsarchus who was scavenging for food. The Andrewsarchus then sniffs at a Puppigerus before the hoofed carnivore kills the turtle with its massive jaws.

The team heads further in land to find other land mammals and eventually spots a herd of rhinoceros-like brontotheres called Embolotherium that were grazing on vegetation in the scrubland. They get the herd back to the park and put into their enclosure, before going to rescue Andrewsarchus. The group soon spots a female Embolotherium trying to her calf not realizing that it is dead from two Andrewsarchus. They set up the portal while the Embolotherium fights off the two carnivores until they were chased away and went through the portal where they were put into their enclosure. Allen soon realized that the time period they visited was at time when the world's climate was changing and that Africa was moving toward Europe and Asia while Antarctica was already freezing in the first time for millions of years and causes the Tethys ocean to disappear along with many of it's sea creatures including Basilosaurus.

He soon went to check on the two Ornithomimus eggs which finally hatch and imprints with him much like modern birds. The park's staff feeds the two Basilosaurus a large amount of fish to regain their strength.
