NEW DATA ON PROCOLOPHONS FROM THE PERMIAN OF EASTERN EUROPE

Abstract

Procolophons from the Upper Permian of Eastern Europe are revised. The genus Microphon Ivachnenko, 1983 established on the basis of a maxilla from the Donguz 6 locality and earlier referred to procolophonids (Procolophonidae) is actually a seymouriamorph; the genera Raphanodon Ivachnenko, 1987 and Raphaniscus Bulanov, 2000 are its junior synonyms. The procolophons (Parareptilia) Nyctiphruretus optabilis sp. nov. (Nyctiphruretidae) and Kinelia broomi gen. et sp. nov. (Procolophonidae, Spondylolestinae) are described based on the jaws from the Upper Permian of European Russia.
