Quaternary Research paper on age of Willamette Valley Megafauna

Edward Davis is a contributing author on a paper in the latest issue of Quaternary research, headed by Danny Gilmour of Portland State University. This study used high-precision AMS radiocarbon dating to determine the ages of the latest megafauna found in the Willamette Valley, here in western Oregon. The dates span the range 15,000 to 13,000 years ago, ending at the onset of the Younger Dryas cold snap but extending well beyond the end of the Missoula Floods, 15,000 years ago.
