| 摘 要： | 近年在南岭以南的广东东江流域河源地区东源县上莞镇的碧寿洞中发现较丰富的古哺乳动物牙齿化石。经鉴定为6个目5属5种,称之为碧寿动物群。根据碧寿动物群指示的古生态、化石层位、热释光测试结果和生物地层对比初步认为,该动物群与西江流域的罗沙岩动物群一样,都属于晚更新世时期的大熊猫—剑齿象动物群,生活在MIS5a时的间冰期,但罗沙岩动物群的时代略早,为(79.0±15)kaBP,而碧寿动物群则存在于末次冰期/末次间冰期之交的MIS5a之末叶。此动物群为广东东江流域历年首现,代表了当时的热带北缘森林草原的自然环境。 |

| Abstract: | Abundant mammal teeth fossils have been found in the Bishou Cave of Shangguan Town of Dongyuan County, Heyuan in the Dongjiang River Valley, south of the Nanling Range, China. We identified 6 new orders and 10 new genera and species of fossils, and furthermore named this area the Bishou Fauna. According to the palaeoecology indicated by the fauna, fossiliferous horizon, TL datings and the bio-stratigraphical correlation, it is preliminariely considered that like the Luoshayan Fauna in the Xijiang River Valley, the Bishou Fauna also belongs to the Late Pleistocene Ailuropoda-Stegodon Fauna, and they lived in the Interglacial Period of MIS5a. However, the age of Luoshayan Fauna about 79 ka B P, is slightly earlier than that of the Bishou Fauna, whereas the Bishou Fauna existed during the close of MIS5a between the Last Glacial and Last Lnterglacial Periods. The fauna is a first discovery in the Dongjiang River Valley, indicating a natural grassland environment on the northern margin of the torrid zone at that time. |
