I won an auction on E-bay which included this brachiopod with no locality info except "France". It's a big fossil that has some damage to it but the preservation style reminds me of the fossils from near Caen, France. I queried some collectors on Facebook and one came back with a tentative ID of Sphenorhynchia sp.
I did an image search on Google and found this page with a specimen called Sphenorhynchia plicatella that seems to match what I have.
Another specimen is pictured on this site.
