Anthropology professor and archaeologist Loren Davis was called to the site. One of the largest bones discovered was a mammoth femur, measuring about 5 feet long. Animals of these species were customary to the Willamette Valley 10,000 years ago or more. Davis and his students have yet to determine the mammoth’s species. There were no artifacts or human bone discovered at the site. The area is not considered an archaeological site. Construction workers were able to get back to work on Tuesday, after the bones were collected. They will be preserved and also carbon dated. The discovery of the ancient mammal bones is not unusual in the Willamette Valley.
