Ryocarhynchus tumidus brachiopod from Belgium

From the Ardennes region of Belgium comes this Ryocarhynchus tumidus brachiopod fossil. It was found in the Matagne Limestone (Fransian stage, Devonian) near the town of Robechies. The shell is round and wider than it is long. The brachial valve is very convex while the pedicle valve is slightly convex at the umbo and grades down to slightly concave in the sulcus. A single, gently dipping sulcus is present but is most pronounced at the anterior margin.

The only other fossil that I have from Belgium is Cyrtospirifer verneuilli.
