Myophorella clavellata (Parkinson 1811) ?

Perhaps the ID Trigonia clavellata Oxfordian Villers sur mer Calvados France that i used is old fashioned? Nice sample Roger!

They belong to the family Trigoniidae. As far as I understand it, they used to be called Trigonia in the good old days, but somebody decided to make things more complicated and split off a new genus Myophorella. That's the up to date name for the ones at Villers now.

Always old fashioned!but i like Trigonia also! thanks Roger!

I agree with you. I like them too. You've got some really nice ones in your collection.

Thanks Roger
