Redondasaurus lived at the very end of the triassic and was one of the largest phytosaurs ever growing larger than modern crocodilians by a considerable margin.The name Redondasaurus is derived from the its location of discovery (Mesa Redonda near Tucumcari, New Mexico) and the Greek word "saurus". This would have been a phytosaur that would have been able to prey on anything it wanted considering its massive size, strong jaws, lack of larger predators in the water and all the large terrestrial carnivores living in the uplands where Redondasaurus wouldn't have been able to go.
The kind of lifestyle this phytosaur would have led would have been remarkably similar to today's large crocodilians like the indian gharial, slender snouted crocodile, freshwater crocodile and the false gharial. Being that these crocodilians all had extremely similarly shaped snouts and sizes. In fact there is no reason to think that it even sounded different from these fearsome reptiles.
This would have been one of the phytosaurs that would have preyed on larger creatures like the dinosaurs that were growing ever bigger and the remaining dicynodonts around. Since most of Pangea was starting to cool down slightly, there were more rivers and lakes around since the Jurassic was on its way there fast! Redondasaurus might not have survived the Triassic extinction given its bulk and need for lots of food every day.
