Hemicyoninae Explained

Hemicyoninae is an extinct subfamily of Ursidae,[1] [2] often called dog bears (literally "half dog" (Greek: Greek, Ancient (to 1453);: ἡμικυων)). They were bear-like carnivorans living in Europe, North America, Africa and Asia during the Oligocene through Miocene epochs 33.9–5.3 Ma, existing for approximately . They are sometimes classified as a separate family.[3]

Systematics

The hemicyonines consists of three tribes: the Cephalogalini, Phoberocyonini, and Hemicyonini. In the past the hemicyonines were evaluated into family level (Hemicyonidae).[3] However the vast majority of papers and researchers that cover the evolution of bears often classified them as an extinct subfamily of ursids or stem-bears.[4] [5] The genus Agriotherium was once classified as a hemicyonine[3] but recent work has shown the genus is a crown-ursid.[6]
