Hemicyoninae is an extinct subfamily of Ursidae[1][2] often called "dog-bears", literally "half dog" (Greek: ἡμικυων "hemi-kuôn"), bear-like carnivoran living in Europe, North America, Africa and Asia during the Oligocene through Miocene epochs 33.9–5.3 Ma, existing for approximately 28.6 million years. They are sometimes classified by some authors as a separate family.[3]
