摘要
1980年夏,作者去甘肃天祝藏族自治县松山公社处理人民来信时,在公社所在地华尖附近发现三个相互邻近的上新世化石地点,其中两个已有相当数量的哺乳动物化石被发掘出来(将另文记述)。本文记述的化石地点位于华兴西南约1.5公里的上庙儿沟村南山坡海拔高度2640米。地理位置是东经103°16′18″,北纬36°57′34″。中国科学院古脊椎动物与古人类研究所野外地点号80006。
Two species of Lagomorphs and four species of Rodents from Loc. 1 of Songshan Commune, Tianzu Xian, Gansu Province, of middle Pliocene in age, are described and compared with those from Pliocene and Pleistocene were found in China, Europe and America. A new species of Ochotonid, which seems to have affinities with the Sanmenian Ochotonoides from North China, may be regarded as the direct ancestry of Ochotonoides complicidens. Three new species and one new subspecies of Rodents are also described. Leptodontomys gansus, Spermophilinus minnutus, Kowalskia gansunica and Prosiphneus licenti tianzuensis. The find of these species or subspecies not only enriches the HipparionFauna found in North China, but also enlarges the possibility to compare it with thosefound in Europe and America.
