Scroll Coprolite

Crappy Date?
United States

This specimen is somewhat enigmatic. It has features that are different from most coprolites in my collection. Because of it's unusual structure and somewhat translucent composition I wasn't 100% sure it was a coprolite. Of course, I knew it wasn't really a fossilized date. But I considered that it could be a cololite (poop before it's pooped), a steinkern, or perhaps even a fish tilly bone.

Fortunately, the experts at The Fossil Forum were able to confirm this is a coprolite, recognizing the scroll structure.
