Archaeological evidence shows that the land that is now Colorado was once home to a prehistoric species called the camelops, a giant camel-like creature that roamed the region alongside mammoths and early humans. Fossils of the camelops, which date back millions of years, have been discovered across the American West, providing insights into Colorado's ancient ecosystem.

Why it matters

The discovery of camelops fossils in Colorado offers a fascinating glimpse into the state's prehistoric past, when it was home to a diverse array of megafauna.

The details

The oldest known camelops fossils date back an estimated 3-4 million years, with the species named by paleontologist Joseph Leidy in 1854 after a fossilized jawbone found in Kansas. In addition to Colorado, camelops remains have been uncovered in several other western U.S. states, indicating the species had a wide geographic range. Scientists believe these giant camels coexisted with early human populations and may have been hunted by them.
