In Oklahoma, low lake levels have uncovered bones which investigators say may be prehistoric.
The bones were found in Lake Eufaula near McAlester, Oklahoma. Medical examiner Angela Berg says the bones belong to two Native Americans and may be 200 to 2,000 years old.
"There's dental wear on these individuals which is more consistent with the use of matates, which is what they used to grind corn, and it would have gravel and small bits of sand in their diet, and then it would wear the teeth down quite a bit," said Berg.
The medical examiner's office will hand over the remains to an archeologist who will then contact Native American tribes to ensure the bodies receive proper burials.
