    S. variabilis is an uncommon echinoid find in North Carolina. At present, to my knowledge there are 2 locations where it can be found. It occurs is the youngest part of the PeeDee. Most of the specimens are crushed or broken, which makes this one special as it is my only complete specimen. Variabilis is a good species name for this, I will be posting 2 others so you can see how variable they can be.
