Palaeagama


Palaeagama is an extinct genus of neodiapsid reptile from the Late Permian or Early Triassic of South Africa.[1] It is based on an articulated skeleton which was probably found in the Early Triassic Lystrosaurus Assemblage Zone, or potentially the Late Permian Daptocephalus Assemblage Zone.[2] Despite the completeness of the specimen, Palaeagama is considered as a "wildcard" taxon of uncertain affinities due to poor preservation.[3] It was originally considered an "eosuchian" (ancestral to modern reptiles),[4] and later reinterpreted as a lizard ancestor closely related to Paliguana and Saurosternon.[2] Modern studies generally consider it an indeterminate neodiapsid,[1][3] though a few phylogenetic analyses tentatively support a position at the base of Lepidosauromorpha.[5][6]
