Scientists have discovered a new dinosaur species at the foot of South America's Andes mountains. The long-necked Eodromaeus, or "dawn runner," searched for prey as the age of dinosaurs began, approximately 230 million years ago.

Researchers have uncovered a new, pint-sized dinosaur that may give paleontologists a better idea of how dinosaurs evolved from their earliest days.

The long-necked Eodromaeus, the “dawn runner,” was about 4 feet long, and weighed only 10 to 15 pounds. It was a carnivore, and a fast runner.

Two individual skeletons were found side-by-side in the foothills of the Andes Mountains in Argentina, in an area known as the “Valley of the Moon.”

National Geographic Explorer-in-Residence Paul Sereno says this discovery gives scientists the ‘earliest look’ at the development
