Sea urchin?
Sea urchin in white calcite?
Awesome!!
I had a answer come back from http://www.rocktumblinghobby.com
I’ve seen some pentagon shaped crinoid stems, but the majority of the ones found here in the SoCal desert are round. Individual pieces may be found, but more likely you see several together, reminding one of stacked poker chips.” Sounds like it could be the answer?
I would disagree with crinoid stem because a) this has many tiny holes next to the circle in the middle, where sea urchin spines may have been, and b) a crinoid stem cross-section will reveal a star-shaped or circular hole in the middle.
Sounds good. But wouldn’t a crinoid stem imprint show up as a post.
