What is "sarmatosuchus"

Sarmatosuchus is an extinct genus of archosauriform reptile found in sediments of early Triassic age and know from the single species Sarmatosuchus otschevi. The holotype and only specimen was found in litified river deposits of the Donguz Formation exposed near the Berdyanka River, Orenburg region, Russia. The genus was originally included in the extinct family Proterosuchidae. However later analysis by David Gower and Andrei Sennikov, the describing author, has removed it from the Proterosuchidae and designated it a basal archosaur.
