近日，位于中国东北辽宁省大连市大连普湾经济区的骆驼山金源洞发现了丰富的新生代晚期化石矿藏。骆驼山金源洞是一个特大型洞穴遗址。金源洞是一个沉积厚度超过40 m的巨大遗址，其不同化石层出土的脊椎动物化石丰富多样，大致可分为3个化石沉积单元，共6个化石层，属于晚上新世至中更新世不同时代。综合生物地层学和年代学证据，金源洞化石组合可分为三个连续的晚新生代动物群（约3.60-0.35Ma）：上部动物群望海动物群（中更新世，0.78-0.35Ma）、中下部动物群金源动物群（早更新世）。更新世，.2.60–0.78 Ma）和最底层动物单元的骆驼山动物群（上新世晚期，3.6–2.6 Ma）。金源洞哺乳动物区系演化可分为新生代晚期的四个时间阶段。新发现的金源洞提供了一个独特的、近乎连续的动物区系和沉积序列，从上新世晚期到中更新世，对建立第四纪具有重要意义。首次结合生物地层学、年代学和探讨东北地区哺乳动物区系序列环境背景
Recently, rich fossiliferous deposits dated to the late Cenozoic have been discovered from Jinyuan Cave at Luotuo.Hill, an extremely large-sized cave site situated within in the Dalian Puwan Economic Zone of Dalian Municipality,.Liaoning Province in Northeast China. Abundant and diverse vertebrate fossils unearthed from different.fossiliferous layers of Jinyuan Cave, a site of enormous size with a sedimentary thickness of over 40 m and its.deposits can be roughly divided into three fossiliferous deposit units, altogether containing six fossiliferous layers.belonging to different ages from the Late Pliocene to the Middle Pleistocene. Based on a combination of.biostratigraphic and geochronological evidence, the fossil assemblages from Jinyuan Cave can be divided into.three successive faunas that span the Late Cenozoic (ca. 3.60–0.35 Ma): the Wanghai fauna from upper faunal.unit (Middle Pleistocene, 0.78–0.35 Ma), the Jinyuan fauna from middle-lower faunal unit (Early Pleistocene,.2.60–0.78 Ma) and the Luotuoshan fauna of the bottommost faunal unit (Late Pliocene, 3.6–2.6 Ma). The.mammalian faunal evolution of Jinyuan Cave can be divided into four temporal stages during the late Cenozoic..The new discovered Jinyuan Cave provides a unique and nearly-continuous faunal and sedimentary sequence.stretching from the Late Pliocene to the Middle Pleistocene, hugely significant for establishing the Quaternary.Mammal Fauna Sequence of Northeast China for the first time based on a combination of biostratigraphy,.geochronology, and for discussing the environmental background
