标题：Zangerlia ukhaachelys, new species, a nanhsiungchelyid turtle from the late Cretaceous of Ukhaa Tolgod, Mongolia. American Museum novitates ; no. 3481
摘要："The late Cretaceous continental deposits of Ukhaa Tolgod, Mongolia, have yielded remains of a new nanhsiungchelyid turtle, Zangerlia ukhaachelys, n.sp. This taxon is based on a single individual that consists of a partial cranium, representatives of all peripherals, an almost complete plastron, and limb fragments. Zangerlia ukhaachelys is diagnosed as a new taxon by the presence of an anteromedial process of the hyoplastron that reduces the typical contact of the entoplastron with the epiplastron. Phylogenetic analysis firmly places Zangerlia ukhaachelys as sister to Zangerlia testudinimorpha and Zangerlia neimongolensis within Nanhsiungchelyidae and confirms the close phylogenetic relationships between Nanhsiungchelys wuchingensis and Anomalochelys angulata and among all North American representatives of Basilemys. In addition, there is modest support that all Asian representatives of Nanhsiungchelyidae form a monophyletic clade, which is primarily diagnosed by a deep, triangular nuc...
