描述了陕西蓝田地区蓝田组底部发现的新罗斯祖鹿化石。该种中等大小,具三分支鹿角,主枝弯曲,角基脊延伸至额骨上;年轻个体的角环与第一分支间距离长,眉枝长且弯曲;下颊齿的古鹿褶不发育或缺失。整理中国发现的祖鹿化石,认为中国晚中新世至早更新世应该有5个种存在:新罗斯祖鹿(Cervavitus novorossiae)、山西祖鹿(C.shanxius)、化德祖鹿(C.huadeensis)、最后祖鹿(C.ultimus)和凤岐祖鹿(C.fenqii)。新的生物年代学数据以及对比分析提示祖鹿可能起源于欧洲,随着东亚夏季风的加强从保德期开始迁入中国。不同于新罗斯祖鹿,山西祖鹿为适应气候与环境改变而出现了较明显的形态改变。上新世之后冬季风的加强致使祖鹿的分布范围越来越小,到更新世早期仅在中国南方有遗存。
A description of the Neo-Rose deer fossils found at the bottom of the Lantian Formation in the Lam Tin area, Shaanxi Province. This medium-sized, with three branches of antlers, the main branch of the bend, the base ridge extending to the frontal bone; young individuals angle ring and the first branch long distance between the long and curved brow branches; Development or absence. Finishing the ancestor fossils found in China, we think there should be five species from China during the Late Miocene to Early Pleistocene: Cervavitus novorossiae, C.shanxius, C. de Zuzu (C. huadeensis, C.ultimus, and C.fenqii. New biogeographic data and comparative analysis suggest that the ancestral deer may originate in Europe and move into China as the East Asian summer monsoon strengthens. Unlike the new Rose deer deer, Shanxi Zude deer to adapt to changes in climate and environment appeared more obvious morphological changes. After the Pliocene, the winter monsoon strengthened the distribution of the ancestors’ deer. Only by the early Pleistocene was the remains only in the south of China.
