Sorry, I've collected ocean shell fossils from the age of Dinosaurs (the time of Tyrannosaurus Rex, to be exact. They are made of chalk. They include fossil sponges, scallops, oysters, sea urchins (sand dollars) and even part of a crab's claw. From another bed, now paved over. I got original oyster shells, not fossilized (some even had parts of the original striping left), Plus, down in South Texas, where my parent's ranch was before it got converted into a lake, there was lots of fossil wood. (That was from after the age of Dinosaurs.) I keep a small collection in my dining room, in a cabinet.
