Eucyon is an extinct genus of medium-sized omnivorous coyote-like canid that first appeared in the Western United States during the late Middle Miocene 10 million years ago. It was the size of a jackal and weighed around 15 kg. It was one of the few North American mammals which invaded Eurasia about 6 million years ago, followed by the genus going extinct 3 million years ago. This genus is proposed to have given rise to genus Canis 6 million years ago.
