尽管中国发现的中新羚(偶蹄目,牛科,蓝牛族)化石较少,但由于其重要的生物年代学意义而备受重视,被作为与欧洲Vallesian期动物群对比的重要分子。描述了新近在陕西府谷喇嘛沟发现的头骨标本。依据下颌骨形态与牙齿特征,将其归入Miotragocerus gregarius (Schlosser,1903)。新发现的材料完善了该种的鉴定特征:中等大小的蓝牛类;角心强烈后倾, 中等分散度,具前后两条棱,横断面呈椭圆形;雄性个体角心前的额骨部分强烈隆升,雌性个体则无明显隆起;脑颅部分成梯形,其最大宽度在角心后,最小宽度在枕骨位置上;基枕骨前后突之间没有沟槽发育;P2与P3具发育且后置的次尖;p4下后尖前后向扩展。对比研究表明,该种较Miotragocerus spectabilis原始,而后者为中国发现的蓝牛类的最后代表且于中新世末期绝灭。对比巴基斯坦以及欧洲的蓝牛,认为中国的Miotragocerus可能与欧洲的种类关系较为密切,而不同于巴基斯坦的Tragoportax。最新的研究资料表明,Miotragocerus在中国主要发现于晚中新世中晚期(Turolian期),可能在8Ma之前从欧洲迁移至东亚,由于剧烈的气候及生态环境的改变于晚中新世末期与Urmiatheriinae等大型牛科化石一起绝灭。
Although the fossils of the Sinnuchus (Cercopithecus, Bovine, and Blue) discovered in China are rare, they are valued by their important biochronological significance and are regarded as important comparisons with the European Vallesian fauna. Describes the skull specimens newly found in Lamaogou, Fugu, Shaanxi Province. Based on mandibular morphology and tooth characteristics, it is classified as Miotragocerus gregarius (Schlosser, 1903). The newly discovered material perfects the identification of this species: medium-sized blue cattle; corner sharp backward, moderate dispersion, with two edges before and after the cross-section was oval; frontal part of the frontal bone of male individuals There was no obvious uplift in females, the trapezoidal part became trapezoidal, the maximum width was at the occipital position after the angle center, and there was no groove developed between the anterior and posterior occipital bone. The development of P2 and P3 Set the next tip; p4 next after the tip of the extension. Comparative studies have shown that the species is more primitive than the Miotragocerus spectabilis, which was the last representative of blue cattle found in China and extinct at the end of the Miocene. Comparing the blue cattle in Pakistan and Europe, it is believed that China’s Miotragocerus may be more closely related to European species than Tragoportax in Pakistan. The latest research shows that Miotragocerus is mainly found in China in the late late Miocene (Turolian period) and may migrate from Europe to East Asia before 8Ma. Due to the drastic climate and ecological changes, Miotragocerus was associated with the late Pleistocene and Urmiatheriinae Large bovine fossils such as extinction.
