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30cm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。
Palaeoloxodon naumanni, Bos primigenius, Bubalus youngi, are abundant in the sediments of ancient Hutuo River, which is 7 ~ 24m underground in the suburbs of Shijiazhuang, Hebei Province. , Coelodonta an-tiquitatis, Cervus sp., Elaphurus sp., Among which the Knotty moulting teeth and the Yang buffalo were the most abundant. Conifer stalks of about 30 cm above the fossil layer are well preserved and can reach a diameter of 20-50 cm with uniform and clear annual rings with a 14C age of 8150 ± 120 a BP. The alluvial layer and the ancient mammalian fossil record the process of cold-wet to dry-heat transition in Shijiazhuang from the late Pleistocene to Holocene.
