摘要

A large series of fossil cercopithecids has been recovered from the hominid-bearing Woranso-Mille site, Afar State, northeastern Ethiopia. Here we report the taxonomy of those specimens from the Am-Ado, Aralee Issie, Korsi Dora, Makah Mera, and Mesgid Dora collection areas, which are all roughly contemporaneous and dated to between 3.6 and 3.8 million years ago. This series includes a minimum of two cercopithecine and three colobine species. Theropithecus oswaldi cf. darti is by far the most common species in the assemblage, making up over 90% of identifiable cercopithecid specimens. There is also at least one other species of papionin, which cannot be currently assigned to a genus. The colobines are here allocated to Cercopithecoides cf. meaveae and two other species, one small and one large, that cannot be currently assigned to genus. The T. oswaldi cf. darti series from Woranso-Mille is both the earliest and largest identified to date. It documents the earliest occurrence of the T. oswaldi lineage and strongly suggests that parallel evolution of molar morphology has occurred within the genus between T. oswaldi and Theropithecus brumpti. Given the dominance of monkeys at Woranso-Mille, and the preponderance of Theropithecus among cercopithecids, T. o. cf. darti is likely to be the most common mammal present at the 3.6e3.8 million-years-old localities of the Woranso-Mille study area. Some explanations for this unusual occurrence are explored, and implications for the paleoenvironment at Woranso-Mille are also discussed.

Woranso-Mille的darti系列是迄今为止确定的最早和最大的系列。它记录了奥斯瓦尔迪氏菌谱系的最早出现，并强烈暗示了摩尔棘齿形态的平行演化已经发生在奥斯瓦尔迪氏菌和布鲁氏菌属之间。考虑到猴子在Woranso-Mille的优势地位，以及Theropithecus在cercopithecids，T. o。中的优势地位。 cf. darti可能是Woranso-Mille研究区360万380万年前的古老哺乳动物。探索了对该异常事件的一些解释，并讨论了对Woranso-Mille的古环境的影响。
