Baskin, J.A.
Carnivora from the late Miocene Love Bone Bed of Florida
2005 Bull.Fla.Mus.Nat.Hist. (45): 413-434
Eleven genera and twelve species of Carnivora are known from the late Miocene Love Bone Bed Local Fauna, Alachua County, Florida. Taxa from there described in detail for the first time include the canid cf. Urocyon sp., the hemicyonine ursid cf. Plithocyon sp., and the mustelids Leptarctus webbi n. sp., Hoplictis sp., and ?Sthenictis near ?S. lacota. Postcrania of the nimravid Barbourofelis indicate that it had a subdigitigrade posture and most likely stalked and ambushed its prey in dense cover. The postcranial morphology of Nimravides (Felidae) is most similar to the jaguar, Panthera onca. The carnivorans strongly support a latest Clarendonian age assignment for the Love Bone Bed. Although the Love Bone Bed local fauna does show some evidence of endemism at the species level, it demonstrates that by the late Clarendonian, Florida had become part of the Clarendonian chronofauna of the midcontinent, in contrast to the higher endemism present in the early Miocene and in the later Miocene and Pliocene of Florida.
