Fossil beach hunt Finale! DOUBLE FOSSIL?!?!??!!?

I got to spend a lovely mild mid-winter day at the local beach and went on an epic hunt for seashells. I Wound up focusing on sea biscuits, which happened to be en masse this particular day.
What are sea biscuits? The sea biscuits found in the Carolinas are fossils of extinct echinoderms, said Coastal Carolina University marine biology professor Rob Young by email. They look like a puffy version of their relative, the sand dollar. Sea biscuits today grow in seagrass beds in the Caribbean and around the world, but no longer live in the Carolinas. The ones on Holden Beach are 34 to 55 million years old, from the Eocene epoch.
