Ohio authorities say bones found in a field above the Mohawk Dam are 900-year-old human remains.
While hunting for arrowheads on June 21, a man stumbled upon the bones and alerted police, The Associated Press reports.
Coroners later revealed they were human. A recent analysis determined they were nearly 1,000 years old.
Coshocton County Sheriff’s Office says the Ohio Bureau of Criminal Investigation has since excavated the site.
The remains now reside at the Licking County Coroner’s Office, where they will continue to investigate the bones.
It seems 2017 is turning out to be a great year for historic discoveries.
Only a few months before the aforementioned bones were found, researchers say they may have found evidence humans lived in North America roughly 130,000 years ago, reports National Geographic.
That's more than 100,000 years before humans were thought to have existed on the continent.
Some experts argue they reportedly found evidence on the Cerutti mastodon site that human activity took place 120,000 to 140,000 years ago in San Diego, California.
The site received national attention after a mastodon skeleton was found there in 1992.
While no human bones have since been discovered, the mastodon skeleton, bone flakes, and several large stones reveals the location was a "bone quarry."
Study leader Tom Demere, paleontologist at the San Diego Natural History Museum, alleges a hominin smashed fresh mastodon bones with stone hammers, perhaps for marrow or raw materials.
"I realize that 130,000 years is a really old date and makes our site the oldest archeological site in the Americas,” says Demere. "Of course, extraordinary claims like this require extraordinary evidence, and we feel like the Cerutti mastodon site presents this evidence."
Meanwhile, during the same month the Ohio remains were found, another explosive discovery shook the world.
In June, The New York Times reported the oldest known remains of Homo sapiens were found across the ocean in Morocco.
Before their discovery, the oldest known remains found were 195,000 years old. In contrast, these Moroccan fossils hail from 300,000 years ago.
The remains astounded experts, who said the findings completely changed the historical narrative that mankind originated from a single location.
"We did not evolve from a single 'cradle of mankind' somewhere in East Africa," said Philipp Gunz, a paleoanthropologist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. "We evolved on the African continent."
