Echinoid- Oligopygus Haldemani

Found the top of this fella in a rock recovered in my North-Central Florida home's driveway.

I believe the scientific name would be Oligopygus Haldemani.

If you guys viewing this have a counter-conclusion, I'd be glad to hear it.

Extracted from Dolostone [CaMg(CO3)3] with a pocket knife.

A good example that you don't have to leave the house to hunt ^^
