Borophagus cf. B. hilli
Alt. Name: bone-cracking dog
Location: Division of Paleontology, American Museum of Natural History
Specimen ID: AMNH 144657
This is a scan of the lower left fourth premolar of Borophagus cf. B. hilli, representing the first known occurrence of borophagine canids from South Carolina, USA. This new fossil record suggests that at least two species of bone-cracking dogs were present in North America at the end of the Pliocene, immediately prior to their extinction. The tooth was collected from the spoiled piles of a commercial quarry by Deborah Young, and donated to the American Museum of Natural History. The paper associated with the specimen is current in press: Tseng, Z.J. and Geisler J. H. The first fossil record of borophagine dogs (Mammalia, Carnivora) from South Carolina, U.S.A.
