Abstract

The Baynunah hippopotamid material provides further evidence for the Hippopotamine Event, which marked the spread and increased ecological impact of the Hippopotaminae into wet habitats across Africa and Eurasia at around 8 Ma. The Baynunah Formation hippopotamid belongs to a hippopotamine species distinct from all other contemporary and later species in having a relatively more elongate symphysis, a feature similar to the earlier (and more primitive) Kenyapotamus. A phylogenetic analysis suggests that this hippopotamine is so far the most primitive for which the mandibular morphology is well known. The morphological affinities of the Baynunah species confirm biogeographic links with Africa and indicate no connection between Afro-Arabian and southern Asian hippopotamids at this time, between 8 and 6 Ma.
