猩猩是濒危的大型类人猿,目前仅生存于印尼的加里曼丹和苏门答腊的热带密林.更新世时猩猩类动物曾广泛分布于我国华南地区及东南亚.研究了最近发现于广西崇左木榄山洞古人类遗址中的大型类人猿牙齿化石,并与现代猩猩、亚化石猩猩及相关古猿进行比较分析,认为这批类人猿牙齿化石可归入猩猩类,但区别于印尼猩猩,表现在牙齿较大,颊齿咬合面釉质皱纹较简单,暂归入猩猩魏氏亚种Pongo pygmaeus weidenreichi.与此同时,分析讨论了华南及近邻越南地区猩猩类动物牙齿变异与分类的复杂性,为探讨华南地区大型类人猿的分类及系统演化提供依据.
The orangutan is an endangered large ape and currently only survives in the tropical jungles of Kalimantan and Sumatra in Indonesia. During the Pleistocene, the orangutan was widely distributed in southern China and Southeast Asia. Compared with the modern apes, the fossil orangutans and the related apes, the fossilized fossils of the apes can be classified into the orangutan, but different from that of the Indonesian orangutan, which is characterized by larger teeth and cheeks The enamel wrinkles on the occlusal surfaces were relatively simple and temporarily classified as Pongo pygmaeus weidenreichi. In the meantime, the complexity of the tooth variation and classification of the orangutan in southern China and neighboring Vietnam was analyzed and discussed. Classification and system evolution to provide the basis.
