摘要
本文对广东罗定、云浮及广西等地的猩猩牙齿化石进行了宏观及微观的形态观察。认为猩猩牙齿咬合面除有较多的褶皱外,大多数标本上还有明显的生长线。化石猩猩牙齿与现生种的相比.牙齿的生长线后者不如前者显著;牙齿的大小是后者小于前者。这些现象表明Hooijer(1948)提出的 Pongo Pygmaeus weidenreichi可以成立。
Fossil teeth of Pongo were discovered in the 1930's in China but they were bought from traditional Chinese medicine stores. Fossils of Pongo found many times afterwards, were only identified as Pongo sp. Eighty-three Orang-Utan teeth derived from Luoding county, Yunfu county in Guangdong Province and some from three localities in Guangxi Zhuang Autonomous Region are reported in this paper.
We found that growth lines appear in the great majority of teeth from P3/4-M3 which have moderate wear and retain wrinkles (crenulations). The morphological characters of these Orang-Utan teeth show that the subspecies Pongo pygmaeus weidenreichi Hooijer 1948 is valid and should be retained.
