Extinct And Fossil Amphibians

This group gathers Amphibians subcategory members that are extinct, known only from fossils, mis-filed into a living-species subcategory by an earlier mint pass. Its members belong to Temnospondyli, an extinct, once highly diverse order of early amphibians that included some of the largest amphibian-grade animals ever to have lived, many with a broad, flattened skull adapted for an ambush-predator lifestyle in rivers, swamps and floodplains, superficially similar in body plan to modern crocodilians despite no close relation to them. Every member of this group is known exclusively through fossil remains and has no living population; the group exists so these clearly non-extant subjects are not counted or displayed alongside the living amphibian species that make up the rest of the Amphibians subcategory.
