Gibbothyris gibbosa from France

A mystery brachiopod from France, labelled Gibbothyris gibbosa, came to me from a seller on E-bay. This specimen comes from near Angoulême in the department of Charente. It was found in sediments that are dated to the Cenomanian stage of the upper Cretaceous.

I am a little confused with this fossil sicne I can't locate any other references to Gibbothyris gibbosa to confirm the ID. I've blogged about Gibbithyris semiglobosa previously but that has a different shape and is slightly younger than this fossil. Any suggestions are welcome.
