Range of Cynarctoides based on fossil record |
Cynarctoides is an extinct genus of terrestrial canine of the family Borophaginae and tribe Phlaocyonini which inhabited most of North America during the Whitneyan stage of the Early Oligocene to the Barstovian stage of the Middle Miocene 33.3—13.6 Mya existing approximately 19.7 million years.
Cynarctoides is derived from the Nothocyon and gave rise to Borophaginae, a short-face, heavy-jawed canine usually massive in size. Cynarctoides shared part of its period with a variety of bear dogs like Aelurodontina, Tomarctus and the giant mustelid genus of bone-crushing canidae.
Cynarctoides was named by P. O. McGrew in 1938 and R. L. Carroll in 1988 and assigned to the family Canidae. Xiaoming Wang later placed it in the Borophaginae genus of Phlaocyonini.
Fossil specimens of two individuals' body mass were examined by Legendre and Roth.
