Today I'm featuring a couple of echinoids from the Eocene aged Ocala Limestone in Florida. First up is Oligopygus haldemani.
Next we have Eupatagus antillarum
Both of these are somewhat common species as I see them posted on E-bay and at fossil shows often. I purchased both of the above specimens from E-bay as comparison specimens so I can better see the differences between the various types of echinoids.
