Temnospondyls were common during Carboniferous, Permian, and Triassic times, and a few species even survived in geographically isolated zones through the Cretaceous. Temnospondyl fossils range in age from 310 to about 112 million years ago, for a total duration of almost 200 million years, 40 million years longer than the dinosaurs. There is disagreement among paleontologists as to whether temnospondyls left no ancestors or evolved into some modern amphibians. Formerly it was thought that they were the ancestors of frogs, but this view has since fallen into disfavor. The typical temnopsondyl had a wide, crocodile-like head and a smaller reptilian body, although there were variants with barrel-shaped bodies, salamander bodies, and alligator-like heads.
