TL;DR: In this paper, all cranial trematosaurid specimens from this locality were assigned to the monotypic genus Inflectosaurus based on the postorbital length of the skull roof.
Abstract: New materials and previously unpublished data on trematosaurid labyrinthodonts from the Early Triassic Bolshoe Bogdo locality (Astrakhan Region) are described. All cranial trematosaurid specimens from this locality are assigned to the monotypic genus Inflectosaurus based on the postorbital length of the skull roof. The diagnosis of the genus is amended. The intermediate position of Inflectosaurus between Angusaurus and Trematosaurus is marked.
