河北阳原、蔚县几个早更新世哺乳动物化石及旧石器地点

桑干河流域,特别是阳原、蔚县盆地的河湖相沉积,不仅发育良好,出露的面积广,厚度大,而且含有丰富的哺乳动物化石。长期以来作为我国北方第四纪早更新世的一个标准地层。近年来在这一地区,在泥河湾地层的下部一些地点,又发现了一些新的哺乳动物化石,并发现了一定数量的旧石器。这有助于进一步确定泥河湾的地层时代,为解决我国北方长期以来第四纪下限问题,为寻找人类化石提供了有利的线索。

SOME NEW FOSSIL LOCALITIES OF EARLY PLEISTOCENE FROM YANGYUAN AND YUXIAN BASINS,NORTHERN HOPEI

This paper gives a preliminary report of Early Pleistocene stratigraphy and the mammalian fossils in Yangyuan and Yuxian districts. All the fossils are from the beds of Nihowan formation. The fossils with similar fauna are also known in Nihowan fauna, which fauna were studied by Teilhard and Piveteau in 1930. The mammalian fossils of Danangou cliff of them are listed in the following:Ly(?)x variabilis Zygolopliodon, sp.Coelodonta antiquitatis Hipparion sp. Paracamelus sp. Antilospira yuxianensis Gazella sinensis(?) Axis sp.From above the list are recognized the Early Pleistoence age. but some of them are discovered for the first time in Nihowan fauna, such as Zygolopliodon, Hipparion, Antilospira. The archaic elements are some survivals of Hipparion fauna of Pliocene age in North China. The discovery of the fossils are of important significance in stratigraphical division. According to these fossils, Nihowan formation is the lowest of Quaternary of the North China.
