10,000-year-old mammoth bones found during construction at OSU football stadium
Construction crews at Oregon State University uncovered a massive femur and other bone fragments belonging to a mammoth Monday.
The bones were found during construction in the end-zone of the Valley Football Center at Reser Stadium in Corvallis.
The mammoth bones are estimated to be about 10,000 years old -- crews also found bone fragments belonging to a camel and bison in the same area.
"There are quite a few bones, and dozens of pieces," said Loren Davis, an associate professor of anthropology at OSU. "Some of the bones are not in very good shape, but some are actually quite well preserved."
Oregon State officials say the findings are not unusual for the Willamette Valley. The area was likely some sort of bog or marsh, Davis said.
"Animals who were sick would often go to a body of water and die there, so it's not unusual to find a group of bones like this," Davis said. "We had all of these types of animals in the Willamette Valley back then."
Because there were no human artifacts or remains found at the site, the bones aren't considered part of an archaeological site.
