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 highly dubious increase in size, the Liopleurodon's weight has also been drastically overestimated. The narrator claims it weighed 150 tons, but more recent studies indicate it wouldn't have been bulky enough to weigh as much. A couple of tons seems to be a more likely estimate, given that we now know that the animal was much smaller than previously thought, though if it had grown to 25 meters, (as the episode suggests) it would have still weighed certainly less than 150 tons.

The narrator states that Liopleurodon can grow up to 25 m long and weighs 150 tons. In reality, no Liopleurodon larger than 7 m has ever been found, and it probably weighed less than 10 tons. See more
