Taxonomy[edit] Carpocyon
Carpocyon was named by Webb in 1969 and assigned to Canidae
Canidae by Webb that same year. In 1988, Carroll assigned it to Canidae
Canidae with X. Wang assigning it to Borophaginae
Borophaginae in 1999. Morphology[edit] Two fossil specimens of Carpocyon
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).[2] Its physical size was between a jackal and a small wolf. Species[edit]

Carpocyon
Carpocyon compressus (synonymous with Cynodesmus cuspidatus) lived 23.13—13.6 Ma, existing for 23.13 million years. Weight of two specimens were estimated at 19.3 kg (43 lb) and 17.6 kg (39 lb) Carpocyon
Carpocyon limosus lived from 16.3—10.3 Ma, existing for 17.97 million years. Carpocyon
Carpocyon robustus lived 13.6—10.3 Ma, existing for 13 million years. Weight of two specimens were 27 kg (60 lb) and 24.3 kg (54 lb). Carpocyon
Carpocyon webbi lived from 16.3—10.3 Ma, existing for 6 million years. Weight of two specimens were estimated at 30.4 kg (67 lb) and 27.2 kg (60 lb)
