摘　　要：系统记述了在2007年从辽宁省朝阳市龙城区马山洞出土的奇蹄目和偶蹄目化石:普氏野马(Equus przewalskii)、马鹿(Cervus(E.)elaphus)、普氏原羚(Proca praprzewalskii)、恰克图转角羚羊(Spirocerus kiakhtensis)、裴氏转角羚羊(Spirocerus peii)和岩羊未定种(Pseudois sp.)。并对马山洞哺乳动物群的性质和年代进行了探讨,指出马山洞动物群含有的北方种类较多,与北方区的很多动物群可以比较,属于典型的北方区动物群。其生态环境为以山地原草地为主,镶嵌有零散的森林,属北温带半湿润-半干旱大陆性季风气候,年平均温度似低于现在。马山洞动物群中绝灭种类不多,主要为晚更新世的类型,在组成上与古龙山、小孤山和阎家岗这3地的动物群最相似,其时代似应为晚更新世中晚期,其绝对年龄估计在5ka左右。A new mammalian fauna was uncovered at Mashandong, Chaoyang Municipality, Liaoning Province. The perissodaetyls and artiodactyls unearthed in 2007 from the Mashandong are systematically described. The identified taxa are as follow： Equus przewalskii, Cervus （ E. ） elaphus, Procapra przewalskii, Spirocerus kiakhtensis, Spirocerus peii, Pseudois sp. The analysis of the Mashandong mammalian fauna showed that it belongs to the Northern Region. Its ecological environment is mainly open grassland with some mosaic forests, and in the semi-humid to semi-arid continental monsoon climate. The average temperature then was slightly lower than that of today. The extinct taxa in the Mashandong fauna are not numerous. The composition of the fauna is close to that of the Gulongshan, Xiaogushan and Yanjiagang, and its age should be between those of these faunas and is estimated about 50ka.
