Hello, I found those echinoids in Upper Campanian strata (SE Pyrenees) The first one I guessed to be an Orthopsis miliaris... But there is a problem. Orthopsis' apical disc is dicyclic, and in my specimen it is hemicyclic. I have numbered the plates as in The Echinoid Directory and the ocular plate "V" lies in contact with the periproct: Other options ? The second one is this small one. I guess Thylechinus, but according to TED this is a problematic genus. Apical disc seems dicyclic (madrepores are clearly visible in G2 plate)
