The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (nomina dubia), or were not formally published (nomina nuda), as well as junior synonyms of more established names, and genera that are no longer considered amphibians.

A trio of three juvenile Diplocaulus in a burrow of eight (plus one juvenile Eryops) were found to have been partially eaten by the sail-backed synapsid Dimetrodon, which likely unearthed the amphibians during a drought. One of the three was killed with a bite to the head, taking part of its skull and portions of the brain, a fatal injury that ...
With their habitat gone, Adelophthalmus dwindled in number and had already gone extinct by the Leonardian stage of the Early Permian.

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 ...
Size estimation of Beelzebufo. In early studies, it is suggested that Beelzebufo had snout-vent lengths of up to 42.5 cm (16.7 in). [1] But in later studies, animals of this species estimated to have grown to at least 23.2 cm (9.1 in) (snout-vent length), which is around the size a modern African bullfrog can reach. [5]
About 280 million years ago, a large creature built somewhat like a salamander but with frightful fangs prowled the swamps and lakes of what is now Namibia, ambushing prey as a top predator in a ...
Similar, but more complex patterns have been found in the oceans. Extinction was more severe among animals living in the water column than among animals living on or in the sea floor. Animals in the water column are almost entirely dependent on primary production from living phytoplankton , while animals on the ocean floor always or sometimes ...
