I have asked that question too and have gotten varied answers. I'd love for someone to point us to a web site or a book about this.

Well, they were there when I started diving there, so they're at least eleven years old.

First you would need to identify the formation (Ocala, Suwannee, Hawthorne, etc...) -- I don't recall it. The ones in the Nest @ 250ish are are 38million years old (if you don't believe the bible).

There are several book on echinoids (sand dollars, sea urchins, etc.) that will show the basic shape, dimensions, etc. I have looked at a few of the books but don't recall the specifics of JB. I will dig a little.

Here is a pretty nice echinoid poster published by the FGS in 1993

Jerry Murphy teaches geology at the university level--maybe he will chime in with a geology lesson for us!!!

I've asked Jerry a few geology questions and he's pretty good at explaining things in a way that's not over my head, but not on a 1st grade science level, either.

Adam, his sn is "Jerry" on here, you might want to send him a PM, I bet you get all the information you want
