Tremarctos is a genus of the monophyletic bear subfamily Tremarctinae, endemic to Americas from the Pliocene to recent. The northern species, the Florida short-faced bear, became extinct 11,000 years ago.[1] The sole living Tremarctos species is the South American spectacled bear. Tremarctos is also the only living genus under the Tremarctinae subfamily, with the other genera, Plionarctos, Arctodus, and Arctotherium all being extinct.
