Auspex Posted November 29, 2014 Share Posted November 29, 2014 Very interesting! What are its dimensions? Can we see the other side too?

Fossildude19 Posted November 29, 2014 Share Posted November 29, 2014 Part of an echinoid, I think.

Cole Posted November 29, 2014 Share Posted November 29, 2014 Beat me to it. Looks like a frag of a large echinoid to me also. Cole~ Knowledge has three degrees-opinion, science, illumination.

Roadrunner Posted December 1, 2014 Share Posted December 1, 2014 (edited) It does look like your link, painshill. Specifically, it also remind me of a "spanish dancer" (sea slug).
