Ursoidea is a superfamily of arctoid carnivoran mammals that includes the families Subparictidae, Amphicynodontidae, and Ursidae. The last family includes the extant lineages of bears, as well as the extinct Hemicyoninae and Ursavinae.
The interrelationships of ursoids has had slight arrangements. In the past it was thought the extinct Amphicyonidae were stem-bears based on morphological analysis of the ear region, though the most recent publications on early amphicyonids suggests they were basal caniforms.
