Pleistocene Black Vultures
Prehistoric species of Black Vulture, Coragyps occidentalis, known as the Pleistocene Black Vulture, feed on carrion two million years ago in what is today the western United States. Pleistocene Black Vultures were very similar to today's American Black Vultures with the exceptions that they were 10-15% larger and had a relatively flatter and wider bills.
Looking on are a pair of camels of the extinct genus Camelops, true camels that resembled the slightly smaller Arabian camels of today.
