Police investigators in the Denver suburb of Aurora on Thursday announced that human bones uncovered at a construction site could be 1,000 years old.

The human remains, which were found Wednesday by a construction crew building a housing development, were determined to be a male of Native American descent and are most likely over 100 years old, if not 1,000 years old, according to the Aurora Police Department's Major Crimes Homicide Unit, the Arapahoe County Coroner's Office and the State of Colorado Archaeologist.

"The Colorado State Archaeologist has assumed responsibility of the remains and the location site, and will be continuing their examination into the bones," according to a press release by the Aurora Police Department.

The area where the bones were found had been an old wagon trail as well as a World War II-era Japanese internment camp, reported KDVR a Fox affiliate in Denver.

While the bones uncovered in Aurora are certainly old, they are not the oldest found on North American soil. In January 2018, remains uncovered in Alaska of a prehistoric indigenous human child were thought to be up to 25,000 years old.

A study released in April 2017 said that humans were in the Americas 130,000 years ago, citing bones found near San Diego.
