Moroccan Calymene/Flexicalymene doubt

Recommended Posts

Are Calymene (those putative specimens from the pictures, existing by thousands at quarry's), a described genera to Morocco or in fact what we got are Flexicalymene. And what species are they?

 

Thanks in advance for your help.

The older literature reported 5 species of 'Calymene' from the Lower Devonian of Morocco, but those have all been reassigned to Gravicalymene.

Flexicalymene is the most common calymenid from the Ordovician of Morocco, but there are others. This one you posted is: Colpocoryphe grandis

 

The smooth pygidial flanks are the key feature for Colpocoryphe.
