Isolated amphibian bones from the early Pliocene of Kanapoi (West Turkana, Kenya) help to improve the scarce fossil record of the late Neogene and Quaternary amphibians from East Africa. All currently available 579 bones are referable exclusively to the Anura (frogs and toads). More than half of the remains (366) are identified as Hemisus cf. Hemisus marmoratus, an extant species that still inhabits Kenya, but apparently not the northwest of the country and the Turkana area in particular. The rest of the remains are identified simply as Anura indet. because of poor preservation or non congruence with the relatively few African extant taxa whose osteology is known in detail. The Hemisus material represents the first fossil record for Hemisotidae, an endemic African family of peculiar, head-first burrowing frogs, whose sister taxon relationships indicate a divergence from brevicipitids in the Late Cretaceous or early Paleocene. The ecological requirements of extant H. marmoratus suggest that the Kanapoi area surrounding the fluvial and deltaic settings, from where the fossil remains of vertebrates were buried, was likely a grassland or relatively dry, open low tree-shrub savanna.

从Kanapoi的上新世早期分离的两栖动物骨骼（肯尼亚西图尔卡纳）有助于改善新近纪晚期和东非第四纪两栖动物的稀有化石记录。当前所有可用的579块骨头仅指阿努拉（青蛙和蟾蜍）。超过遗骸（366）的一半被认定为Hemisus比照 Hemisus marmoratus，一种仍在肯尼亚居住的现存物种，但显然不是该国的西北地区，尤其不是图尔卡纳地区。其余的遗骸被简单地识别为阿努拉indet。由于保存较差或与较少的非洲现存分类单元不一致，该分类单元的骨科学已为人所知。该Hemisus该材料代表了Hemisotidae的第一个化石记录，He​​misotidae是一种非洲特有的，头先挖洞的青蛙特有的家庭，其姊妹分类关系表明其与白垩纪晚期或古新世早期的evi虫科动物不同。现存的H. marmoratus的生态学要求表明，围绕河流和三角洲地区的Kanapoi地区可能是草原或相对干燥，开放的低矮树型稀树大草原，这些地区埋藏着脊椎动物的化石。
