1963年7月19日,中国科学院古脊椎动物与古人类研究所的一个野外考察队,在陝西省西安市东南的藍田县泄湖人民公社陈家窩村的第四紀紅色土层內,发掘出了一个猿人的下颌骨。这是迄今为止我国发現的最完好的猿人下頜骨,是研究人类起源的一个新的宝貴的科学材料。与猿人化石一起,还发現了豺、虎、古象、野猪、斑鹿等許多哺乳动物化石。埋藏这些化石的土层厚約三十米,其下有一层一米多厚的礫石层。猿人下頜骨化石就埋在紅色土层的底部,靠近礫石层的地方。在离猿人化石大約一千米的同一地
On July 19, 1963, a field expedition of the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences was excavated in the Quaternary red soil layer of Chenjiawo Village, Xiehu People’s Commune, Lantian County, southeast of Xi’an, Shaanxi Province. A jawbone’s mandible is out. This is the finest mandible found in China so far and is a new valuable scientific material for the study of human origin. Along with the fossils of the Deaf people, many fossils of mammals such as pheasants, tigers, ancient elephants, wild boars, and spotted deer were found. The buried earth layer of these fossils is about thirty meters thick, and there is a layer of gravel with more than one meter thick. The fossils of the mandibular jaw were buried at the bottom of the red soil near the gravel layer. About one kilometer from the Buddhist fossil
