本文描述了两个新采自晚中新世Namurungule组的thryonomyids标本。一个是有槽的上门齿，这是指Paraulacodus sp。另一个是臼齿，有三个横向lophs，其明确的分类位置不能确定。Namurungule组和埃塞俄比亚的Chorora组之间的啮齿动物区系的相似性。这与两个地层的放射性年龄的近似一致性是一致的。
Two specimens of thryonomyids newly collected from the Late Miocene Namurungule Formation are described. One is a grooved upper incisor, which is referred to Paraulacodus sp. Another is a molar with three transverse lophs, whose definite taxonomic position can not be determined. The similarity in the rodent faunas between the N amurungule Formation and the Ch'orora Formation of Ethiopia is suggested. It is concordant with the approximate coincidence of the radiometric ages of both formations.
