Tapocyon ("dog from Tapo Canyon") is an extinct genus of placental mammals from clade Carnivoraformes, that lived in North America during the middle Eocene.J. J. Flynn (1998.) "Early Cenozoic Carnivora ("Miacoidea")." In C. M. Janis, K. M. Scott, and L. L. Jacobs (eds.) "Evolution of Tertiary Mammals of North America. Volume 1: Terrestrial Carnivores, Ungulates, and Ungulatelike Mammals." Cambridge University Press, Cambridge. Tapocyon was about the size of a coyote and is believed to have been a good climber that spent a lot of time in trees.
