Echinolampas ?

It would be better with an origin and an age...

The one on the left looks like that to me. the one on the right is different though. Can you post a shot of the underside of each please?

Hello Al Dente,

Thank you for your help. Actually I saw on google that Eupatagus has an orifice however the one I have doesn't present any. Any further explanations ?

It is probably under the matrix !

I agree with Coco that the orifice is either under the matrix or maybe part of the fossil is broken off. All echinoids have 2 orifices, one where food enters (peristome) and one where waste is expelled (periproct).

You are right ! I found an orifice and the other one is probably on the second spot.
