|Range of Carpocyon based on fossil distribution|
Carpocyon is an extinct member of the Borophaginae, and a terrestrial canine (bear-dog) which inhabited most of North America during the Barstovian stage of the Middle Miocene through the Hemphillian stage of the Late Miocene epoch 13.6 to 5.3 Ma Mya. Carpocyon existed for approximately .
Carpocyon was named by Webb in 1969 and assigned to Canidae by Webb that same year. In 1988, Carroll assigned it to Canidae with X. Wang assigning it to Borophagina in 1999.
Two fossil specimens of Carpocyon were measured by Legendre and Roth in 1988. They estimated that specimen one weighed 24.1 kg (53 lb) and the second weighed 21.8 kg (48 lb). Its physical size was between a jackal and a small wolf.
- Carpocyon compressus (synonymous with Cynodesmus cuspidatus) lived 23.13—13.6 Ma, existing for . Weight of two specimens were estimated at 19.3 kg (43 lb) and 17.6 kg (39 lb)
- Carpocyon limosus lived from 16.3—10.3 Ma, existing for .
- Carpocyon robustus lived 13.6—10.3 Ma, existing for . Weight of two specimens were 27 kg (60 lb) and 24.3 kg (54 lb).
- Carpocyon webbi lived from 16.3—10.3 Ma, existing for . Weight of two specimens were estimated at 30.4 kg (67 lb) and 27.2 kg (60 lb)
