Deinodonbufo

Deinodonbufo is an extinct species of brachyopoid temnospondyl amphibian in the family Chigutisauridae. It was the last ever temnospondyl to have ever lived, living in what is now Argentina and Brazil during the Late Cretaceous from 97 million years ago to 66 million years ago. It survived competition from crocodilians by becoming a filter-feeder, feeding on much smaller animals, shellfish-eater, feeding on crustaceans and such, and being an egg-eater as one fossil suggests. It was also among the biggest known amphibian species on Earth, about 20 feet in length from nosetip to tailtip, about the size of a modern day saltwater crocodile, probably weighing very similar. It was once thought that Deinodonbufo was just very similar to a Koolasuchus (which lived before Deinodonbufo evolved), only bigger and having different teeth, but newer fossils with bony armor lying nearby had been discovered, so it is possible that it had armor covering throughout its body, as protection against most predators and competitors, such as crocodilians. New fossil evidence suggests that Deinodonbufo was almost entirely aquatic to avoid most competition from crocodilians that hunt on both land and in water. Despite these adaptations, this extinct amphibian sadly did not make it though the extinction at the end of the Age of Dinosaurs.
