I found this at the Wilson Clay Pit in July of 2015. I'm not sure what it is. Its quite small, approximately 8 millimeters. It doesn't have the look of a crinoid stem or brachials. Is it from a crinoid? Is it possibly a echinoid spine of some type? It is from the Harpersville Formation, Late Pennsylvanian, Virgilian Stage (288 to 286 MYA).
The specimen is below. The scale is in centimeters.
Any help is appreciated, as always...
