I am working at a local museum now, the Gorge Heritage Museum in Bingen, Washington. Today I had a local visitor and his mother who brought 3 fossilized teeth in to show me. They are hoping to identify what the teeth may be. I am guessing Bovine style from the looks, but presumably much older than cows. They are also quite large. Fascinating! I really enjoyed looking at them and holding their heavy smooth weight in my hands. Here are photos in case anyone has a lead for me!
