The Cooperton Site
Mammoth ribs at the Cooperton site
The Cooperton mammoth site contains the remnants of
a young male Columbian mammoth which died sometime from 17,000 to
21,000 years ago. This site was excavated by the Museum of Great
Plains at Lawton in 1961. Intriguingly, while excavating the mammoth,
three hand-sized stones and a 15 pound boulder were uncovered near
the skeleton.. Additionally, some of the bones bear break marks
that occurred while the bones were still relatively fresh.
The investigators concluded that the mammoth had died
from natural causes and had been discovered by a small band of hunters.
They believe the three stones (which are much larger than other
cobbles found in the area) were used to crush the bones on the boulder
(which appears to have been brought into the site) to extract marrow
The stones themselves do not show clear evidence of
human manufacture and so the conclusions of the investigators may
never be proved or disproved. The oldest accepted human habitation
site in the Americas is the Monte
Verde site in Chile which is generally accepted at an age of
12,500 years ago.
