天津蓟县晚更新世象化石分布与地貌特征

描述和对比了天津蓟县晚更新世地层发现的纳玛象、诺氏象第二门齿及第三臼齿化石,由于4处化石发现地均在天津蓟县，相互之间距离很近，且都在山前丘陵和平原区内，故具有一定的地域特点，小范围内发现古菱齿象属的2个种，在北方具有一定代表性，说明在晚更新世温暖期中，蓟县由于特殊地貌所形成的森林茂盛、淡水充沛、气候温和的特点，更适合象及其他如鹿、牛、羊等大型哺乳动物的生长和繁殖．

The distribution of elephant fossils and the physiognomy characters of late Pleistocene in Jixian County of Tianjin

Several fossils which were the second fore-tooth and the third cheek tooth of Paleoloxodon naumanni and Paleoloxodon namadicus found in late Pleistocene stratum in Jixan County of Tianjin are described and contrasted. Four fossilsdiscovered areas have the certain terrain characteristics because they are apart from a few kilometers mutually and locate in the knap and plains before mountains. The two species of Paleoloxodon found in a small area are of a typical in North China. It is showed that the ecological environment of Jixian County was overly suited for the living and multiplication of the elephants and the large mammal animals such as deer, cattle and sheep etc in the warmly late Pleis- tocene epoch, due to the physiognomy characters, e.g. flourishing forests, the flush freshwater and mild climate.
