摘要： 初步对辽宁省建平县北二十家子镇附近出土的第四纪哺乳动物化石进行分析，结果为形成于新生代中更新世的温暖潮湿的草原生态系统的肿骨鹿鹿角化石.鹿角化石硅化较强，通过区域地层与化石对比，研究区内的鹿角化石时代形成于中更新统早期.鹿角化石埋藏于黄土地层中，黄土为干燥寒冷的草原环境产物，分析得出研究区出现过温暖潮湿的气候环境，此后长期以干燥寒冷的气候环境为主，进而推测哺乳动物受气候影响变化较大，乃至灭绝.

Abstract: Based on a preliminary analysis of the Quaternary mammalian fossils unearthed near North ErshiJiazi Town in Jianping County， of Liaoning Province， it was found that these fossiles are the antlers of megaloceros， developed from the warm humid steppe ecosystem during the Cenozoic midPleistocene. By a contrast study of regional stratigraphy and other fossils， these fossils with strong siliconization were formed in the early Pleistocene. The antler fossils were buried in the loess soil， a product of the dry and cold weather conditions， so the studied area had been warm and humid， and became dry and cold hereafter. It might be concluded that the mammals were affected more by climate changes and finally died out.

Key words: west of Liaoning province, megaloceros, fossil, Quaternary, contrast
