Fossil specimens have been recovered in the United States, Canada, Mongolia, China, and at least one species in Korea. Harpagolestes exhibits strong, curved canine teeth, a deep lower jaw, massive skull, and heavy wear on the molars. This along with stout limb bones suggest that Harpagolestes was a scavenger and did not pursue its prey. The wear on the molars suggests it regularly cracked bones.
