Workers digging for a project to expand Oregon State University’s football stadium were startled to stumble across 10,000-year-old mammoth bones.
The construction crews uncovered a large femur bone, and later found more bones from several extinct mammals, including some kind of camel or horse.
“There are quite a few bones, and dozens of pieces,” said Loren Davis, an associate professor of anthropology at OSU who was called to the site after the initial discovery was made, in a statement. “Some of the bones are not in very good shape, but some are actually quite well preserved.
