Leptocyon (Greek: slender dog[1]) is a small extinct genus of canid endemic to North America during the Oligocene through Miocene living from 24.8—10.3 mya, existing for approximately 15.5 million years.[2]
Leptocyon was a small bodied, fox-like animal with a slender jaw.[3]
Taxonomy[edit]
Leptocyon was named by Matthew (1918). It was synonymized subjectively with Vulpes by Gregory (1942); it was revalidated by Webb (1969), Carroll (1988) and Munthe (1998). It was assigned to Canidae by Matthew (1918), Webb (1969), Carroll (1988) and Munthe (1998).[4][5]
Morphology[edit]
