Molecular data analyses blew the problem of hippo origins up to the level of a broader question: cetacean and artiodactyl relationships. Recently, new morphology-based studies strongly supported a hippo origin within Miocene bothriodontines, which are selenodont anthracotheres. Based on these results, two new scenarios for hippo emergence are proposed here. Palaeoenvironmental and evolutionary issues...
This study analyses the carnivore component of African fossil faunas from three time slices: 7–5Ma, 4–3Ma, and 2.5–1.2Ma, using cluster analysis and principal coordinate analysis (PCO) of presence/absence data on genera. The faunas mostly cluster by time slice, with the exception of Laetoli (Tanzania) and Ahl al Oughlam (Morocco), which differ from all other faunas. The separation during the Late...
