The Anatomy, Paleobiology, and Phylogenetic Relationships of the Hippopotamidae (Mammalia, Artiodactyla) from the Manonga Valley, Tanzania

Part of the Topics in Geobiology book series (TGBI, volume 14)

Abstract

Hippopotamids are well represented in the Manonga Valley fauna, composing 23.4% of all large mammals, and they are second in importance only to bovids. Several species of hippopotamids are represented. The material from the Ibole and Tinde Members, with the exception of a single postcranial specimen, can be assigned to Hexaprotodon harvardi, a large hexaprotodont hippopotamid, which is relatively common at late Miocene and early Pliocene sites in East Africa (Harrison, 1993). The remaining specimen from the Tinde Member, an isolated phalanx, apparently belongs to a smaller species of Hexaprotodon. The taxo-nomic affinities of the hippopotamids from the overlying Kiloleli Member are more difficult to ascertain because so few specimens have been recovered. Even though they are most reasonably referred to Hex. harvardi, they differ in some minor details from the type material, and it is conceivable that they may represent a somewhat more progressive form. In addition to Neogene hippopotamids, several isolated teeth and some postcranial remains of Hippopotamus have been recovered from late Quaternary horizons. Apart from a brief discussion of their biochronological implications, these latter specimens are not included in the following analysis.
