摘要
过去认为涝池河—阳郭动物群的时代相当或稍晚于泥河湾动物群，早于公王岭动物群，厚镇涝池河动物群的时代与公王岭动物群的一致。但各动物群的层位及在动物群演化上所处的位置表明涝池河—阳郭动物群的时代应与公王岭动物群的一致，比泥河湾动物群的晚，而厚镇涝池河动物群的时代应与陈家窝动物群的相当。重新厘定了公王岭期与陈家窝期的涵义，认为蓝田黄土地层中、早更新统的界线应划在Ｓ８与Ｌ９交界处。
It was usually considered that the age of the Laochihe and Yangguo faunas should be the same as/or a little later than that of Nihewan fauna,and earlier than that of the Gongwangling fauna.It was also considered that the Houzhen fauna should be related to the Gongwangling fauna.However,both the stratigraphic positions of these mammalian faunas and their evolutional positions show that the age of the Laochihe and Yangguo faunas should be the same as that of the Gongwangling fauna,and that the Houzhen fauna should be related to the Chengjiawo fauna. The Gongwangling Stage and Chengjiawo Stage are redefined in this paper. The Gongwangling Stage from 1.4—0.9 Ma B.P. including Gongwangling fauna,Laochihe fauna and Yangguo fauna in Lantian could be correlated with the Late Villafranchian in Europe or with Irvingtonian I in North America,while the Chengjiawo Stage from 0.9—0.5 Ma B.P. including the Chengjiawo fauna and the Houzhen fauna could correspond to Galerian in Europe or to Irvingtonian Ⅱ in North America.The boundary between Middle and Early Pleistocene in Laochihe loess section should be the S 8/L 9 boundary
