| †Desmatosuchus spurensis|
PaleobiologyEditDesmatosuchus shows a resemblance to the ankylosaurid dinosaurs such as Ankylosaurus, but it isn't very related to them, and is a much older species. It was heavily armoured, with even its under-belly protected. Not even ankylosaurs had that. It had a long snout made for digging through the ground and pulling up roots and shrubs. It had a plated, whip-like tail that was designed to whip predators and keep them away. It's back was completely covered in armor plating, and not even the large Phytosaur Rutiodon could have bitten through it. The plates were a second defense if a predator could even get past its 18 in. (45 cm.) shoulder spikes. It lived in either forested areas or desert land, and lived alongside herbivores like Placerias and Plateosaurus, predators like Coelophysis, Rutiodon, and Postosuchus, and also small protomammals like Megazostrodon.
In the MediaEditDesmatosuchus made an appearance in When Dinosaurs Roamed America, and drove off a Rutiodon and Coelophysis. It also starred in Animal Armageddon, where it shows how it became extinct during the Triassic Extinction and was overwhelmed by Triassic dinosaurs called Staurikosaurus.
