Within the last few years, new archaeological discoveries have continued to push back the timescales on when humans are believed to have initially arrived in the Americas.
There, archaeologists discovered a collection of a mastodon - an extinct species of elephant - bones along with stones which appeared to have been scraped and hammered.
However, no other traces of human activity in the region, so researchers were left scratching their heads over the anomaly.
But a new survey from researchers has discovered ancient mastodon bones in the region which were embedded into the upward facing sides of two cobblestones collected from the site.
According to the new research, the data suggests that the bones were indeed hammered in using rocks - a technique which is presumably unique to humans.
