Renowned zoologist Nigel Marven plunges into the prehistoric deep to face some of the largest and most fearsome sea predators that ever existed – creatures so awesome, they make the great white shark look like a goldfish. Scour the depths of seven different prehistoric seas with Nigel as your guide – and marvel at the computer animation techniques that bring each aquatic world to life. Get up close and personal with creatures like the vicious sea scorpions of 450 million years ago, the armor-plated fish of the Devonian Period and a whale-chomping shark called Megalodon. Finally, wade out into the deadliest sea of all time – "Hell's Aquarium" of the late Cretaceous, an ominous body of prehistoric water that gets its name from its elevated water temperatures and the devilish creatures that call it home.

Sea Monsters: A Walking with Dinosaurs Trilogy - Sea Monsters (TV series) - Netflix
Sea Monsters is a 2003 BBC television trilogy which used computer-generated imagery to show past life in Earth's seas. In the U.S. it was known as Chased by Sea Monsters. It was made by Impossible Pictures, the creators of Walking with Dinosaurs, Walking with Beasts and Walking with Monsters. In the series, the British wildlife presenter Nigel Marven is shown traveling to seven past seas in the history of the Earth and scuba diving there, in order of dangerousness with the most dangerous last. He travels in a white sailboat or motorboat roughly 24 m (80 ft) long named 'The Ancient Mariner'. His time travelling device is not mentioned or shown, and the closest thing to it is his time map, showing the timeline of the seven deadliest seas and the creatures that lived at the time. He uses a scuba set with a fullface mask so he can talk underwater to produce the commentary. He performs some dives using a strong shark cage, which is spherical to make it harder for large sea creatures to bite it.

T-rex did not live 75 Mya though the Tyrannosaurid might be Lythronax it still look's a lot like the T-Rex from Walking with Dinosaurs. Liopleurodon was smaller and Odobenocetops did not live during the Pliocene as the genus was thought to have gone extinct before the Pliocene it was restricted to the Miocene. Cymbospondylus would mostly eat cephalopods and turn apart tender meat and fish, not entire thick reptile tails. Mosasaurids and other marine reptiles had flukes. Basilosaurus was unable to swim in deep water due to a study of its vertebrate.
