Platyoposaurus was a Temnospondyli amphibian from the Middle Permian period about 270-268 Mya.
One of the discoveries includes a skull 28 cm long with a purported body length of 250 cm representing a carnivorous adult specimen.
The fossil remains were found in Belebey, Bashkortostan in Russia, and the name Platyposaurus means "flat faced reptile".
