A New Lindholmemydid Turtle (Testudines: Lindholmemydidae) from the Bayn Shire Formation (Late Cretaceous) of Mongolia

Vladimir B. Sukhanov, Igor G. Danilov, Pagam Narmandakh

Abstract


Paragravemys erratica gen. et sp. nov. is described from the lower part of the Bayn Shire Formation (late Cretaceous, Cenomanian – Turonian) of Mongolia. This new genus differs from other lindholmemydids by unique pattern of inframarginals which include two wide and two narrow scutes on each side and by a sinuous medial sulcus on the plastron. Unlike known lindholmemydids with four pairs of inframarginals (with possible exception of Elkemys) the third inframarginal in the new genus is restricted to the hypoplastron.
