Early Pleistocene mammals from Yeka locality in Shangri-La,northwestern Yunnan
摘要
Abstract
The Early Pleistocene Yeka Fauna was first identified during the Hengduan Mountains Scientific Expedition in the 1980s.New mammal fossil remains were collected during the execution of the Second Tibetan Plateau Scientific Expedition and Research Project(STEP)in 2020 and 2024.The most recent findings have been identified as 5 orders,12 families,15 genera,and 15 species.The updated Shangri-La fossil mammal combination(Yeka and Zhongdian faunas)has been compared to several Early Pleistocene faunas in China.It has been found to be most closely correlated to the Yuanmou Man Fauna.The faunal composition of the Shangri-La fossil mammal combination is distinguished by the co-occurrence of boreal and austral elements,a pattern that is analogous to the modern biogeography observed in the Hengduan Mountains.Faunal analysis suggests that during the Early Pleistocene,the Shangri-La region was characterized by a moderate-elevation forest intermingled with open grassland.关键词
