广西南宁渐新世基于咽齿的鲤亚科一新属
Cyprinus-like pharyngeal bones and teeth (Teleostei, Cypriniformes, Cyprinidae) from the Early-Middle Oligocene deposits of South China
摘要
Abstract
Here we describe +Nanningocyprinus wui gen.et sp.nov,a fossil Cyprinus-like fish from the Early-Middle Oligocene deposits of Langdong,Nanning Basin,Guangxi Province,South China.+Nanningocyprinus wui is represented by a number of pharyngeal bones and teeth.It differs from all other cyprinid fishes in the following character combination:tooth formula -3·2· 1,crushing molar-like A 1 much larger than A2,only one groove on the grinding surface of A2 and B1 respectively,and the anterior angle of the pharyngeal bone triangular and prominent.The new-found Cyprinus-like fish,along with the previously known Late Eocene +Eoprocypris maomingensis (Procypris-like) and Oligocene ++Huashancyprinus robustispinus (Cyprinus-like) from South China,further indicates an early branching and diversification of the Cyprininae (Cyprinidae) in this area.关键词
