Paranaschisma ("near Anaschisma") is an extinct genus of temnospondyls. These animals were part of the family called Metoposauridae, which filled the crocodile-like predatory niches in the late Triassic.
Taxonomy
[edit]Paranaschisma was originally named as a new species of Buettneria, B. howardensis, by Sawin (1944) on the basis of a a number of skulls from Otis Chalk Quarry 3 in Howard County, Texas.[1] A number of later authors variously synonymized B. howardensis with Metoposaurus fraasi or M. jonesi.[2][3] Long and Murry (1995) synonymized B. howardensis with Buettneria perfecta.[4] In 2026, howardensis was found to be distinct from Tecovaserpeton and given a new genus name, Paranaschisma.[5]
