Stone "nut" near Vierves sur Viroin (Be)

[2Ronalds]

In addition to my earlier query on stone "nuts" from Vireux, I found another "nut" near Vierves sur Viroin (Be). It is with 20mm much longer. The split is almost inconspicious at 3 mm and I cannot see a "tongue" inside. It also differs by having six paralel and very shallow trenches and seven low and blunt ridges back to front on its top surface. Some remaining materal between the rock and the fossil suggests we're looking at an internal mould. This one must be from another family alltogether from the 2 specimen from Vireux.

Again can anyone tell me what I am looking at.

The director of Geological Enterprises, a firm that claims to have the largest collection of fossils for sale in the world, confirmed the photos show internal brachiopod moulds. Next question of cause is, of which species.

Is there anyone who knows an article that lists the Brachiopod species for the location near Vierves sur Viroin? I haven't been able to find one on the internet so far.
