In this article a fragment of a right lower canine, found at the gravel pit Hooge Broek near Raalte (province of Overijssel, the Netherlands) in Rhine sediments at a depth of at least 20 metres below the surface, is described. It is recognised to belong to a Hippopotamus incognitus Fauré, 1983, and to be of probable Eemian age or slightly later (Late Pleistocene). Part of the enamel shows a rugose, lizard skin-like texture, thought to be a primitive trait, as in the recent pygmy hippo Choeropsis, and in some hexaprotodontic hippopotami from the Early Pleistocene.
