A new species of hippopotamus Hexaprotodon lothagamensis(Mammalia: Hippopotamidae) from the late Miocene of Kenya
Abstract
A new small to medium-sized hippopotamus, Hexaprotodon lothagamensis is described from the late Miocene of northern Kenya. The material was recovered from Lothagam, a site southwest of Lake Turkana. This narrow-muzzled hippopotamus differs from other Hexaprotodon species in terms of its small size and shallow symphysis. The six incisors are arranged in a straight line across the front of the jaw and the lower canines are almost aligned with the cheek tooth row. H. lothagamensis compares more closely to an Arabian species, Hexaprotodon aff. H. sahabiensis from the late Miocene, than to any other African Hexaprotodon. The phylogeny of the Hippopotamidae is discussed and although the genera names are maintained, the genus Hexaprotodon is paraphyletic. Hexaprotodon lothagamensis appears to be less derived than the extant pygmy hippopotamus, H. (Choeropsis) liberiensis, which was previously considered to be a living fossil.

“C. liberiensis has low-crowned molars, further supporting its status as a forest-dwelling consumer of coarse vegetation (Weston 2000).”

In the citing paper
“The earliest remains that unequivocally resemble extant hippos appeared in the fossil record in the late Miocene, around 8 million years ago (Weston 2000), and later within this period its range also extended into parts of Eurasia (Boisserie 2005).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
