摘要:基于安徽省潜山盆地大量新材料,对安徽龟属(Anhuichelys Yeh,1979)进行了系统再研究,将其归入了陆龟科基干类型(Testudinidae)。安徽龟属包含了潜山盆地古新统地层中的三个种:产自下古新统望虎墩组的小市安徽龟(A.siaoshihensis Yeh,1979), 望虎墩组和痘姆组的潜山安徽龟(A. tsienshanensis Yeh, 1979)以及中古新统痘姆组的新种痘姆安徽龟(A. doumuensis sp. nov.)。产自湖北新洲古新统的新洲安徽龟(A. xinzhouensis Chen, 1983)为潜山安徽龟的晚出同物异名。作为陆相脊椎动物群的成员,安徽龟很可能是一种陆生龟类并且是第一个甲壳具有铰链的陆龟超科成员。

Abstract Our systematic revision of Anhuichelys Yeh, 1979, based on abundant new material from the Paleocene of Qianshan Basin, Anhui Province, China provides evidences for its assignment to the stem Testudinidae. Anhuichelys contains three species in the Paleocene of Qianshan Basin: A. siaoshihensis Yeh, 1979 from the Early Paleocene of Wanghudun Formation, A. tsienshanensis Yeh, 1979 from both Wanghudun and Doumu formations and A. doumuensis sp. nov. from the Middle Paleocene Doumu Formation. A. xinzhouensis Chen, 1983 from the Paleocene of Xinzhou, Hubei Province is synonymized with A. tsienshanensis. Associated with a terrestrial vertebrate fauna, Anhuichelys is likely a land turtle and also the first testudinoid to develop the hinge on the shell.
