The first known representatives of the family Hippopotamidae left a limited fossil record during the Miocene. In this chapter, two assemblages of hippopotamus remains are identified in the late Miocene of the Middle Awash. The first one was recovered from the Asa Koma Member of the Adu-Asa Formation, dated to 5.5 to 5.8 Ma. The second set came from the Kuseralee Member of the Sagantole Formation, from sandstones just below the 92-15 basalt (dated to 5.2 Ma). The recent discoveries of new late Miocene and early Pliocene hippopotamid material in the Middle Awash study area constitute an important step in understanding this crucial period for Hippopotamidae and, more generally, their evolution in the Afar basin.
