孙家洞是一处重要的旧石器时代早期洞穴遗址。2012年5～10月,由洛阳市文物考古研究院和栾川县文管所共同发掘。该遗址中有明确地层的标本有9699件,其中含有大量的动物化石,少量的石制品和动物粪便化石,最重要的是发现了6颗古人类牙齿化石,其中4枚为单颗牙齿,另外两颗分别附着在上颌骨和下颌骨残块上。而淘洗和采集的没有明确地层的标本则数以万计。该遗址的发现有利于我们全面认识中国旧石器早期文化面貌和中更新世时期过渡区域的动物群,为研究中国第四纪古生物的演化、古气候环境的变化提供了重要资料,对于研究人类起源及演化有着重要的科学意义。
Sun Cave is an important Paleolithic cave site. From May to October 2012, it was jointly explored by Luoyang Institute of Cultural Relics and Archeology and Luanchuan County Wen Guan. There are 9699 well-defined samples of the site, which contain a large number of animal fossils, small quantities of stone products and animal faecal fossils, the most important is the discovery of six ancient human teeth fossils, of which four are single teeth, the other Two were attached to the maxillary and mandibular residual fragments. However, there are tens of thousands of specimens that are not eluviated and collected by panning. The discovery of this site will help us to fully understand the fauna of the early Paleolithic and transitional regions during the mid-Pleistocene in China, providing important information for studying the evolution of Quaternary Paleontology in China and the paleoclimatic and environmental changes. And evolution has important scientific significance.
