摘　　要：河北省石家庄市郊区地下7～24m的古滹沱河沉积物中产出丰富的大型哺乳类化石:诺氏古菱齿象(Palaeoloxodon naumanni)、原始牛(Bos primigenius)、杨氏水牛(Bubalus youngi)、披毛犀(Coelodonta an-tiquitatis)、鹿(Cervus sp.)、四不像鹿(Elaphurus sp.)等,其中以诺氏古菱齿象和杨氏水牛数量最为丰富。在该化石层之上约30cm处的针叶树茎杆保存完整,直径可达20～50cm,年轮均匀清晰,14C年龄为8150±120a BP。冲积层及其中的古哺乳类化石记录了晚更新世最晚期向全新世过渡期间石家庄地区由冷湿向干热转变的过程。Occurring at 7 - 24 m below the surface of current deposits of the ancient Hutuo River, the excavated fossils in the suburb of Shijiazhuang include Palaeoloxodon naumanni, Bubalus youngi, Bos primigenius, Coelodonta antiquitatis, Cervus sp., Elaphurus sp. etc., among which the most abun- dant forms are Palaeoloxodon naumanni and Bubalus youngi, which coexist with fossil conifers in the same sequence in Hutuo River deposits. A ~4C age date of 8150＋120 a BP is obtained from a fossil conifer, whose diameter varying between 20 cm and 50 cm, containing sensitive tree-ring. The macro-mammalian fauna records the climate change from temperate cold to warm, humid to arid in Shijiazhuang area from the later Late Pleistocene to the Holocene.
