摘要:

白龙洞是位于鄂西北部郧西县的一处出土物丰富的古人类洞穴遗址,先后在此出土了8枚古人类牙齿化石、若干石制品和骨制品及大量哺乳动物化石。但有关白龙洞遗址的形成时间却一直存在争议,主要原因之一是动物群没有得到充分研究。基于郧西县文管所和中科院古脊椎所收藏标本,本文首次对白龙洞历年出土的哺乳动物化石进行了综合研究;研究结果表明,白龙洞动物群由32种(含未定种)哺乳动物组成,优势属种是谷氏大额牛、岩羊、野猪及各种鹿类(水鹿、斑鹿、麂、毛冠鹿);此外,还有豪猪、竹鼠、变异狼、貉、豺、猪獾、黑熊、大熊猫、中国硕鬣狗、锯齿剑齿虎、虎、豹、金猫、云豹、剑齿象、苏门犀、梅氏犀、巨貘、鬣羚及水牛等;该动物群缺乏猴类动物,并且豪猪化石也很少,这与其所处的时空位置很不相符;但总体面貌属于大熊猫-剑齿象动物群。白龙洞的大熊猫、中国硕鬣狗、猪獾、虎及巨貘的牙齿测量数值均达到或接近我国各自记录的最大值。白龙洞动物群组成与盐井沟动物群及南京猿人动物群最为接近;从动物群组合及有关属种的演化阶段来综合判断,白龙洞动物群的地质时代应当是中更新世中期。

Abstract:

Bailongdong (or Bailong Cave), a cave site of ancient humans, is positioned at Yunxi County which is located in the northwest part of Hubei Province. The principal archaeological finds from Bailongdong include 8 human teeth, a couple of stone and bone artifacts as well as numerous mammalian fossils. Whereas the geologic age of the site is still debateful so far, mainly because of the evidence from the mammalian fossils were not well explored. This study covers all the available specimens unearthed during the past four decades, which are currently reposited in the Cultural Relics Station of Yunxi County and the Institute of Vertebrate Paleontology and Paleoanthropology of CAS. The results show that the Bailongdong fauna is composed of 32 mammalian species (including undetermined species) which is dominated by Bos(Bibos) gaurus grangeri, Pseudois nayaur, Sus lydekkeri and diversified deers (Elaphodus cephalophus, Muntiacus cf. reevesi, Muntiacus muntjak, Cervus grayi, Rusa unicolor); In addition, the following taxa are also presented: Miniopterus schreibersii, Rhinolophus sp., Ochotona sp., Leopoldamys edwardsi, Rhizomys sinensis, Hystrix subcristata, Canis mosbachensis variabilis, Cuon javanicus antiquus, Nyctereutes sinensis, Ursus thibetanus, Ailuropoda baconi, Arctonyx collaris rostratus, Pachycrocuta sinensis, Catopuma temmincki, Neofelis nebulosa, Panthera tigris, Panthera pardus, Homotherium sp., Stegodon orientalis, Dicerorhinus sumatrensis, Stephanorhinus kirchbergensis, Megatapirus augustus, Capricornis sumatraensis kanjereus and Bubalus sp., and the extinct taxa account for 43.75%; but monkeys are lacking and porcupines are few, which is unusual for its geographical and chronological positions; moreover, the general composition agrees well with that of the Ailuropoda-Stegodon fauna. Such taxa of Bailongdong fauna as A. baconi, P. sinensis, A. c. rostratus, P. tigris and M. augustus nearly reached the maximum peak in dimensions of their kinds respectively. Based on the faunal composition and evolutionary levels, the age of Bailongdong fauna should correspond to the Middle Pleistocene, which is very close to the Yanjinggou fauna and the fauna of the Nanjing Man site.
