About Pseudocyon
Pseudocyon (False dog) is a genus of amphicyonid which inhabited Eurasia and North America during the Miocene epoch from 17.2 to 9 Ma. Pseudocyon was assigned to Amphicyoninae by Hunt in 1988. The genus was one of the largest amphicyonids with the North American Pseudocyon possibly weighing 773 kg (1,704 lb).
Originally evolving in Europe, Pseudocyon dispersed into North America roughly 15.5 Ma, replacing Amphicyon ingens.
