摘 要:The first Sinomastodon(Gomphotheriidae,Proboscidea) skull of the Early Pleistocene,collected from the Renzidong Cave deposits in Anhui Province,Eastern China,is described here as *** *** the only brevirostrine trilophodont gomphotheriid known from the Old World,Sinomastodon was mainly indigenous to China from the Early Pliocene to the *** with a few single Pleistocene teeth previously found in China,*** *** represented by a relatively complete skull,mandible and dentition,which is the first discovery of a Quaternary Sinomastodon skull from *** a brevirostrine,elephant-like skull,no lower tusks,and simple bunodont and trilophodont intermediate molars,the new species is morphologically distinct from other gomphotheres and should belong to the genus *** new species is more progressive than *** and the Pliocene type species *** in its skull and mandible morphology,but is evidently more primitive than the Pleistocene *** in its molar *** faunal analysis suggests that the emergence of *** *** Jiangnan area and its southward migration may have been related to a cooling event at the beginning of the Quaternary in Eastern China.
