Families

Ursoidea is a superfamily of arctoid carnivoran mammals that includes the families Subparictidae, [1] [2] Amphicynodontidae, [3] [2] and Ursidae. The last family includes the extant lineages of bears, as well as the extinct Hemicyoninae [4] [5] and Ursavinae. [6]

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, [7] though the most recent publications on early amphicyonids suggests they were basal caniforms. [8] [9] [10]

The amphicynodontids are sometimes classified as either a subfamily of bears, [3] a paraphyletic assemblage of early bears, [2] or even stem-pinnipeds. [11] [12] [13] The subparictids were previously classified as amphicynodontine/ids. [2] The hemicyonines have been occasionally reclassified as a separate family. [14]
