Ursinae is a subfamily of Ursidae (bears) named by Swainson (1835) though probably named before Hunt 1998. It was assigned to Ursidae by Bjork (1970), Hunt (1998) and Jin et al. (2007).[1][2][3]
Classification[edit]
The genera Melursus and Helarctos are sometimes also included in Ursus. The Asiatic black bear and the polar bear used to be placed in their own genera, Selenarctos and Thalarctos; these are now placed at subgenus rank.
