Walking with Monsters

There are many animals known only from the screen for many people. Petrolacosaurus is a prominent member of this group of animals as many only know it from its appearance in the Walking with Monsters series. Despite its dinosaur-like name, Petrolacosaurus was a small reptile and, as we can see from the first clip featuring it, at the mercy of many other animals like the enormous amphibians, arthropods, and insects it was contemporaneous with. The second clip shows that not all of these interactions went poorly for Petrolacosaurus though. The small predatory reptile was the beneficiary of tragic natural events like forest fires (as shown) and was capable of running down prey smaller than itself.
