The earliest branch of the Canidae was the Hesperocyoninae lineage, which included the coyote-sized Mesocyon of the Oligocene (38-24 Mya). These early canids probably evolved for fast pursuit of prey in a grassland habitat, and resembled modern civets in appearance. Hesperocyonine dogs became extinct except for the Nothocyon and Leptocyon branches. These branches lead to the borophagine and canine radiations.
