甘肃华池马兰黄土中的哺乳动物化石

<正> 1985年10月,原华池县党校张文忠同志,在校址旁的柔远城子下挖窑洞时,于马兰黄土中发现一批化石,庆阳地区博物馆于同年11月组织了发掘.1986年1月,笔者同往华池,进一步观察了地层.鉴于我国北方马兰黄土中发现的化石很少,在此给予简要报道

SOME MAMMALIAN FOSSILS FROM MALAN LOESS,HUACHI, GANSU

The mammalian fossils described in this paper were collected by Qingyang District Museum from Rouyuan town of Huachi County, Gansu, in 1985. They are stored in Gansu Provincial Museum. The mammalian fossils consist of the following species: Felis tigris, Crocuta ultima, Equus hemionus, E. przewalskyi, Coelodonta antiquitatis, Cervus (E.) canadensis, Gazella przewalskyi And Bos primigenius. Crocuta uhima is generally considered as an index fossil form of Late Pleistocene in north China. The age of the mammalian fossils described above may be considered as Late Pleistocene. The mammalian fossils were buried in silt clay with grayish white and yellow tints. The lithology is basically consistent with that of Malan loess of north China. We infer here that these mammals lived in a grassland habitat of temperate zone with a few trees in its eastern border area adjacent to the mountain known as Ziwu in present days.
