英文摘要	Salamanders are a model system for studying the rates and patterns of the evolution of new anatomical structures(1-4). Recent discoveries of abundant Late Jurassic and Early Cretaceous salamanders are helping to address these issues(5-8). Here we report the discovery of well-preserved Middle Jurassic salamanders from China, which constitutes the earliest known record of crown-group urodeles (living salamanders and their closest relatives). The new specimens are from the volcanic deposits of the Jiulongshan Formation (Bathonian)(9-13), Inner Mongolia, China, and represent basal members of the Cryptobranchidae, a family that includes the endangered Asian giant salamander (Andrias) and the North American hellbender (Cryptobranchus). These fossils document a Mesozoic record of the Cryptobranchidae, predating the previous record of the group by some 100 million years(14-17). This discovery provides evidence to support the hypothesis that the divergence of the Cryptobranchidae from the Hynobiidae had taken place in Asia before the Middle Jurassic period.; Multidisciplinary Sciences; SCI(E); EI; PubMed; 0; ARTICLE; 6930; 424-428; 422
