Pyrocyon ("fire dog") is an extinct genus of small carnivorous placental mammals from extinct order Hyaenodonta, that lived in North America during the early Eocene. Fossils of Pyrocyon have been found in Wyoming and Colorado.^[6] Weight of Pyrocyon dioctetus has been estimated at around 2.6 kilograms.^[7]
