Looks like an Olennellus. You should see the one I got from my Geology professor that came from the Fruitville Quarry, Lancaster, Pa. About 550 million years old.
It really does look like Nancy Pelosi, Helen Thomas, and Cindy Sheehan, collectively. No wonder we call them “old fossils”.
Beautiful trilobite....Rana pipiens. When fossilized coiled it looks like a frog. Just beautiful. Devonian
Trilobites aren’t mollusks.
