Abstract

Based on fragmentary remains (incomplete lower jaw and premaxilla) from the Lower Triassic Kamennyi Dol locality (Kamennyi Yar Formation, Rybinskian Horizon) of Obshchii Syrt (Samara Region) and a number of specimens from the same region, a new genus and species of trematosauroid temnospondyls, Qantas samarensis gen. et sp. nov., is described. It displays a mosaic combination of typical benthosuchid and trematosaurid characters, remaining in general structure of the lower jaw at the benthosuchid evolutionary level, so that a new benthosuchid subfamily, Qantasinae subfam. nov., representing an isolated lineage, is established. Based on the cranial remains of trematosaurid temnospondyls from the Cynognathus Zone of South Africa, which were previously described by Shishkin and Welman (1994), a new trematosaurine genus and species, Trematosuchoides africanus gen. et sp. nov., is established.
