Oxfordshire, U.K.- 149 million years B.C. This episode follows a shoal of young fish-like Ophthalmosaurus as they struggle to survive the Late Jurassic seas, evading predators like the gigantic Liopleurodon. On land, the dinosaur Eustreptospondylus scrapes out a living as a scavenger, occasionally preying on pterosaurs like Rhamphorhynchus. Written by

Aside from its somewhat dubious increase in size, the Liopleurodon's weight also seems to have been drastically overestimated. The narrator claims it weighs 150 tons, more recent studies indicate it wouldn't have been bulky enough to weigh as much. 30 tons seems to be a more likely estimate, though if the animal really did grow to 25 meters, as the episode suggests, it may have weighed more, but certainly less than 150 tons.
