I know that's actually a mint press issue for pennies! (I'm just kidding, that's awesome! I'm not educated in the field but is that a fossil of a prehistoric sponge? I found a flower or leaf at Yellowstone that was amazingly preserved)

Crinoids are echinoderms related to starfish and sand dollars. Think of them as a starfish on a stem.

That's so cool! So they could move like starfish and weren't stationary like a corral? I'm going to guess it is a filter feeder too? Sorry for all the questions, I'm a huge fossil fan since elementary

Some had a root like holdfast and were stuck in one place. Others could crawl around on the sea floor. Most modern crinoids don't have a stem and swim. youtu.be/cZcomBnNKXg?...
