New material of Cervidae (Artiodactyla, Mammalia) from?Xinyaozi Ravine in Shanxi, North China

Abstracts

Many cervid specimens were uncovered during the field exploration for Nihewan beds?at the beginning of the 1980s from Taijiaping, Shuichongkou and Dazhuangke localities along?Xinyaozi Ravine at Nangaoya Township of Tianzhen County, Shanxi Province in North China.?Recent studies on the cervid material identified seven species of Cervidae in total: Muntiacus?bohlini, Cervavitus cf. C. huadeensis, Axis shansius, Nipponicervus elegans, Elaphurus?davidianus predavidianus, E. bifurcatus from the Early Pleistocene deposits at Taijiaping and?Shuichongkou localities, and Cervus (Elaphus) elaphus from uncertain horizon at Dazhuangke. At?least the previous six species of cervids were from Nihewan Formation (Nihewanian or equivalent?to European middle and late Villafranchian), i.e. the Early Pleistocene, in Sangganhe Basin area.Cervavitus cf. C. huadeensis and A. shansius were survivors from the Late Neogene; M. bohlini,N. elegans, E. davidianus predavidianus and E. bifurcatus are new forms of the Early Pleistocene.If Dazhuangke horizon can be dated as those of Shuichongkou and Taijiaping localities, the appearance of elaphoid cervids could be traced back to the Early Pleistocene, and the evolution of?elaphoid antler would start from absence to presence of bez tine. The presence of Elaphurus and?Nipponicervus in mainland China and Japanese archipelago implies further that the sea level was?dropped down that these cervids could migrate from the mainland to the islands. The abundance?of folivorous cervid specimens in the Xinyaozi Ravine area indicates the existence of a certain?scale of forested environment in Sangganhe Basin area during the Early Pleistocene.
