This new series deals with recent discoveries and the kinds of terrible lizards not much was known about in the past. The star of episode one was a Spinosaurus, all the way from North Africa, a carnivore that looked like a crocodile with distended legs and a hunchback. At 18 metres long, it wasn't the sort of thing you'd like to bump into!
