From Wikipedia, the free encyclopedia
Apterodon ("without winged tooth") is an extinct genus of hyaenodonts from extinct subfamily Apterodontinae within paraphyletic family Hyainailouridae, that lived from the late Eocene to the early Oligocene epoch in Africa and Europe.[3][9] Including supplementary materials It is closely related to the African Quasiapterodon.[3]

Uniquely among hyaenodonts, species of Apterodon were semiaquatic, fossorial mammals. They possessed strong forelimbs that were well equipped for digging, compared to those of modern badgers, while the tail, torso and hindlimbs show adaptations similar to those of other aquatic mammals like otters and pinnipeds. The dentition was suited to feed on hard-shelled invertebrate prey, such as crustaceans and shellfish. They probably lived along African coastlines.[3]
Dental analysis found that within Apterodon macrognathus, the dental eruption of secondary dentition occurred much more slowly than in carnivorans.[10]
