Jiangxichelys, a new nanhsiungchelyid turtle from the Late Cretaceous of Ganzhou, Jiangxi Province, China

摘要

A new taxon of nanhsiungchelyid turtle, Jiangxichelys ganzhouensis n. g. n. sp., is described on the basis of a complete shell from the latest Cretaceous of Ganzhou, Jiangxi Province, China. It is close to Hanbodgemys, but different from the latter in having a boot-shaped second marginal scute reaching the first vertebral scute, a larger first suprapygal, a large fifth vertebral extending onto the tenth peripheral, narrower lateral marginal scutes and a narrower posterior plastral lobe. This discovery adds a new element to the scanty record of nanhsiungchelyids from southern China and illustrates the diversity of the family in that area.
