A sample of 117 fossil cercopithecids has been collected from the Middle Pleistocene site of Asbole, Afar Region, Ethiopia. A minimum of five species is present. There are two species of Cercopithecini, here recognized as cf. Chlorocebus aff. aethiops, and cf. Chlorocebus cf. patas. There are also two species of Papionini: Papio hamadryas ssp. indet. and Theropithecus oswaldi leakeyi. Finally, there is a single species of colobine present, Colobus sp. indet. The assemblage is chronologically constrained and is derived from sediments dated to approximately 600 ka. Within this sample Colobus sp. is by far the most common species present, outnumbering the other four species combined. The cercopithecid assemblage is most consistent with a woodland habitat, corroborating an earlier interpretation based on the non-primate fauna. Taxonomic, biogeographic, and evolutionary implications of the assemblage are also discussed.
从埃塞俄比亚阿法尔地区阿斯博勒的中更新世遗址采集了117份猕猴科化石样本。至少有五个物种。有两种猕猴属动物，这里分别认定为疑似阿比西尼亚绿猴和疑似赤猴。还有两种狒狒属动物：未确定亚种的阿拉伯狒狒和莱基奥氏草原狒狒。最后，有一个未确定种类的疣猴属物种，未确定的疣猴。该组合在时间上受到限制，来自约60万年的沉积物。在这个样本中，未确定的疣猴是目前最常见的物种，数量超过其他四种物种的总和。猕猴科组合与林地栖息地最为一致，这证实了基于非灵长类动物群的早期解释。还讨论了该组合在分类学、生物地理学和进化方面的意义。
