周口店田园洞大中型哺乳动物记述

田园洞古人类化石地点含不少动物化石，其中主要为大中型哺乳动物，并以鹿类为主。除一枚残破鬣狗牙齿以外，目前在此所发现的材料全可归入现生种。该地点主体堆积的地质时代可能与周口店山顶洞动物群同期。本化石组合中有几个种现在已经离开本地区，如貂、黑熊、香麝、梅花鹿、马鹿、牛及鬣羚等，它们可能代表了这些动物在北京地区的最晚记录。但有些动物却是北京地区的首次发现，例如猪獾和鬣羚。

LARGE MAMMAL FOSSILS FROM THE TIANYUAN CAVE, A HUMAN FOSSIL SITE OF END-PLEISTOCENE AGE RECENTLY DISCOVERED NEAR ZHOUKOUDIAN

Tianyuan Cave is a human fossil-bearing site found recently outside of the core area of prehistoric localities in Zhoukoudian area. The newly discovered site is also very rich in large mammal fossils, most of which are cervids. Until now, all the mammal fossils recovered here can be included into the living forms except a broken tooth of Crocuta. The geologic age of the new site can be correlated with that of the Upper Cave at Zhoukoudian. Some elements of the mammal fauna have become disappeared from this region nowadays, they are Martes sp., Ursus thibetanus, Moschus moschiferus, Cervus nippon, Bos sp. and Capricornis sp. The fossil evidence of all these mammal species mentioned above may represent the latest records of their existence in Beijing area. But some elements are the first records of their appearance in Beijing area, such as Arctonyx collaris and Capricornis sp., both of them are oriental animals.
