Abstract: A new species of large bovid Shaanxispira, S. baheensis is briefly described. The materials were found from the middle part of the Bahe Formation, Lantian County, China. S. baheensis is characterized by having straight horn cores with a clockwise twisted keel on the right, positioned behind the orbit. The braincase is rather short in respect to the width, and the cranial axis is at about 90°with the facial axis. The occipital surface is wide and flat with a wide mastoid exposure. No basal pillars on the labial side of lower and on the lingual side of upper molars. The phylogenetic relationships of the Shaanxispira with some other large bovids are also tentatively discussed. There possibly existed a group of large bovid of tribal or subfamilial level that died out during the late Miocene, which includes the Urmiatherium, Plesiaddax, Hezhengia, Shaanxispira, and possibly Sinotragus.
摘要: 1997~2001 年,中科院古脊椎动物与古人类研究所与芬兰赫尔辛基大学合作,于灞河组地层中发现哺乳动物化石计45 种。其中牛科化石种类与蓬蒂期典型三趾马动物群中的种类不同,至少存在分别归属于Shaanxispira、Protoryx、Dorcadoryx和Gazella 的4个新的种类。本文仅记述其中陕西转角羚羊一新种:灞河陕西转角羚(Shaanxispira baheensis sp. nov. ) 。 该种主要鉴定特征:角心长而直,粗壮,横断面呈圆形,具一条发育的棱,起始于前内侧,右角上呈顺
