Description

edit

Bystrowisuchus flerovi is based on a holotype specimen including six cervical or neck vertebrae and a partial right ilium or hip bone. Its total body length is estimated at 2 to 3 metres (6.6 to 9.8 ft).[1]

Discovery

edit

The holotype specimen of Bystrowisuchus was found near the eastern banks of the Don River in Ilovlinsky District, Volgograd Oblast. It came from a fossil site known as the Donskaya Luka locality, which preserves a wide diversity of Early Triassic tetrapod fossils. Along with Bystrowisuchus, the Donskaya Luka fossil assemblage includes temnospondyl amphibians, a chroniosuchian, a procolophonid, a sauropterygian, a protorosaurian, possible trilophosaurid archosauromorphs, two rauisuchid archosaurs, and a dicynodont. Elongated neural spines previously attributed to the rauisuchid Scythosuchus basileus may belong instead to Bystrowisuchus.[1]
