Hello,
I need your help to identify this XXL schizaster!
the biggest ones that I found have the approximate size of: 2.5 inch (65 mm) but this is huge!
Found earlier this week in "zanclean" in the Pyrenees Orientales in France. The colors originate, I think, from iron oxides.
I thought of eurynotus or major but without certainty.
Thank you in advance for your input.
