甘肃和政地区麝牛亚科一新属的初步报道

邱占祥, 王伴月, 颉光普   

Abstract: In September 1998, while visiting the museum of the Linxia Hui Autonomous Prefecture, we saw a number of skulls with apparent ovibovine affinity in the museum' s storeroom. A few days later we found skulls of the same animal in a dragon—bone digger' s closet mixed up with other skulls and bones of common elements of the Hipparion fauna. Although imperfect in preservation, we obtained the best ones from the dragon—bone digger. In January 1 999, when Qiu and Xie were invited by the Hezheng county authorities to identify the fossils they acquired in the past few years, we finally realized that this unrecorded ovibovine animal should be one of the most characteristic forms of the Hipparion fauna of the whole Hezheng district (including the neighboring counties of Guanghe and Dongxiang). Among the thousand odd fossils, most of which were perfectly preserved skulls, 170 skulls are referable to this animal, the second largest group in number next only to the chilotheres. Elaborative study of this material needs, and has been planned, to be done in special monographs on systematic basis. Since this important ovibovine animal has never been known to science, a preliminary report is given below.

摘要: 麝牛亚科新属新种Hezhengia bohlini是和政地区三趾马动物群中最特征的动物之一。其主要特征是:角心粗短无角柄,断面三角形,表面多沟槽,角先向侧后方伸出,再向前并微微向下伸展;顶骨面和枕骨面形成约150°之角;眼眶向外突出弱;牙齿次高冠,上前臼齿相对较长。Hezhengia虽然在麝牛亚科中的地位不容质疑,但它和其他各属的关系暂时还不清楚。
