So I found these fossils around Tukwila Washington. I'm not looking for an ID but I'd just like to share with you some of the gastropods and bivalves I found along the way And for all you Washington fossil hunters, don't listen to people who say you need to be in Utah to find fossils, they are everywhere here (Information: These come from the Eocene time period 40 million years ago. Some of these fossils are Turritella Uvasana (Identified by Professional) some gastropods, some pecten looking shells (still not sure) and bivalves of unknown species.)
