Morphogenesis and age-related structure of permanent canine teeth in the brown bear, Ursus arctos L., in Arctic Alaska

Abstract.

Morphogenesis of the canine teeth of the brown bear, Ursus arctos L., is described, based upon 101 skulls from the central Brooks Range, in arctic Alaska. The formation of annual layers in the calcified tissues (dentin and cementum) is attributed to interruption of growth and odontogenesis during the annual period of denning.
