Brought my son out to my new secret spot in Contra Costa County, SF East Bay Area, CA (thankfully NOT within any park boundaries). The spot is a deep creek bed around a border where Eocene (Tdu/Domingene form.) and Early Cretaceous (Kbs) meet. There are lots of nice gastropod fossils in large masses of sandstone, a few brachiopods here and there, but my favorites are the many quite large bivalve fossils and whole oyster fossils we found. Today my son spotted a really nice cluster of large bivalves peaking out the wall of the creek bed, and he found another whole oyster! He was so thrilled.
