Johnston's Coyote (Canis lepophagus) is an extinct species of canidae which was endemic to much of North America and lived from the Miocene epoch through Early Pleistocene, 10.3—1.8 Mya.[1]. The Johnston's Coyote existed for approximately .
Canid competitors
The Johnston's Coyote lived during a period with other canidae, specifically Borophaginae such as Epicyon (20.6—5.330 Ma), Paratomarctus (16.3—5.3 Ma), Borophagus (23.3—3.6 Ma), Carpocyon (20.4—3.9 Ma), and Aelurodon (23.03—4.9 Ma).
Fossil distribution
The Johnston's Coyote was named by Johnson in 1938. The first fossil record was found in Cita Canyon, Texas. Subsequent discoveries of specimens were found in 4 other Texas sites, Tonuco Mountain, New Mexico, western Washington[2] Sante Fe River, Florida,[3] Black Ranch in northern California, sites in Nebraska, Idaho, Utah, and Oklahoma.
A specimen was estimated by Legendre and Roth to weigh 18.5 kg (40.7 lbs) and another specimen was estimated to weigh 17 kg (37.4 lbs).[4]
