This list of prehistoric amphibians is an attempt to create a comprehensive listing of all genera from the fossil record that have ever been considered to be ...
Platyhystrix (from Greek: πλατύς platús, 'flat' and Greek: ῠ̔́στρῐξ hústrix, 'porcupine') is an extinct temnospondyl amphibian with a distinctive sail along its back, similar to the unrelated synapsids, Dimetrodon and Edaphosaurus. It lived during the boundary between the latest Carboniferous and earliest Permian periods ...
Swallowing was done by tipping the head back, as seen in many modern amphibians and in crocodiles. Evolution of a deeper skull, better jaw control and a reduction of the palatine tusks is only seen in the more advanced reptile-like forms, possibly in connection with the evolution of more effective breathing, allowing for a more refined hunting ...
Paleontologists with the Smithsonian National Museum of Natural History have discovered a previously unknown prehistoric species — a 270 million-year-old amphibian with wide eyes and a ...
Prionosuchus has been classified as an archegosaurid by Carroll. [6] The genus is monotypic with P. plummeri being the only species described. The archegosaurs were a group of temnospondyls that occupied the ecological niche of crocodiles and alligators during the Permian, and of which the European genus Archegosaurus is typical.
Other Megalocephalus fossils found in the 1860s had been referred to other large amphibians, namely Pteroplax and Anthracosaurus. Two well-preserved skulls and associated jaw bones were found in Newsham in 1870 and 1871, though these were also mistakenly referred to a pre-existing genus, Loxomma. In 1873, Thomas P. Barkas named a pair of new ...
The pieces are now reunited, creating a single 5.5-inch-long, 5.1-inch-wide tooth that came from one of the world’s most fearsome predators — a prehistoric shark that reached nearly 60 feet in ...
