Leptocyon 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.[1]

Leptocyon was a small bodied, fox-like animal with a slender jaw.[2]

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).[3][4]

Morphology[edit]

Body mass[edit]

Two specimens were examined by Legendre and Roth. Estimated body mass of these two was 3.26 kg (7.2 lb)[5]
