I'm in Northern Arizona in an area full of crinoid, bryozoan, and brachiopod fossils. Recently I found what I believe might be a cyclocrinite. It's round, about the size of my thumb, and pitted like a golf ball. Its been suggested that this might be a calyx from a crinoid but since the hexagons on my fossil extend inward and not outward, I have my doubts. It looks like this thing was trapped in a pocket when it was fossilized. You can even see some space between the fossil and the material around it. The last picture shows the section of the stack that broke off, revealing the fossil inside. I thought about cracking it open but I'm concerned about damaging the fossil. Any thoughts on what this might be? If its not a cyclocrinite my other theory is that some poor caveman lost his golf ball in a water hazard on a 500 million years ago. I'm new to the forum and you guys are the experts here so any help would be appreciated!
