中中新世沉积物分配到Muruyur层已经产生了丰富的动物群遗骸，这表明一个时代附近的中中新世早期的一部分，也许是早于特尔南堡的时间，但可能是同时代或稍晚于马博科。现有的放射性同位素年龄测定表明，这些岩层的年龄在1350万年至1400万年之间。老，这似乎是太年轻时相比，生物地层的估计。穆鲁尤尔层的重要性在于其丰富的化石内容，其中包括在东非化石记录中普遍缺乏代表性的时代的人科动物。本文将化石的发现记录在案，并讨论其地质背景。
The middle Miocene sediments assigned to the Muruyur Beds have yielded abundant faunal remains which indicate an age somewhere near the early part of the middle Miocene, perhaps being earlier in time than Fort Ternan but probably coeval or slightly later than Maboko. Available radioisotopic age determinations suggest that the beds are between 13.5 and 14 m.y. old, which seems to be too young when compared with the biostratigraphic estimate. The importance of Muruyur Beds lies in their rich fossil content which includes hominoids of an age which is in general poorly represented in East Africa’s fossil record. This article places the fossil discoveries on record, and discusses their geological context.
