An oil company drilling in western Oklahoma has stumbled across a deposit of camel and horse fossils that date back roughly five million to 12 million years.
The Oklahoman reports that the fossils belong to an extinct species of camel and horse. They were found in July in the Packsaddle Wildlife Management Area.
One of the fossils discovered is a well-preserved horse skull that is tinier than its present-day descendant.
A machine operator for Apache Corp., the Houston-based oil company drilling in Packsaddle, discovered the fossils after clearing away roughly 20 feet of earth.
A team of paleontologists and archeologists has uncovered 13 separate pits containing deposits of bones of varying sizes.
