Palaeobiology
Locomotion
Prolimnocyon atavus was well adapted for scansorial locomotion. Its hindlimbs contained adaptations such as a cuboid was characterised by a helical proximal cuboid facet, a talus possessing a flattened talar trochlea with a high lateral rim, and a medially projecting lesser trochanter on its femur. On its forelimbs, its humerus had a prominent deltopectoral crest and a reduced greater tubercle, while its radius possessed an ovoid radial head, and its ulna had a radial notch that was oriented laterally. The species also possessed ungual phalanges that were laterally compressed and moderately deep.[9]
