Dinosaur skeleton: "The Terror of the Triassic Swamps: Phytosaurs were large, aquatic reptiles that lived in and along rivers and swamps about 210 million years ago. Phytosaurs resembled crocodiles but were not ancestral to them. This skull came from an animal that was nearly twenty feet in length. Long jaws lined with sharp teeth indicate that phytosaurs were meat-eaters and would have been able to prey on any animal unlucky enough to gt too close."
