Fossil ID - help with age/type of a shell

[Stimon]

Found this, what looks like a shell in granite. Riverbed in Wallonia, south of Belgium. River, the Ourthe (or Semois). Any chance this could be named or roughly dated?

According to this geologic map: 

 

 

It looks like maybe the area is mostly Lower Devonian in age - so around 400 million years old. 

 

The brachiopod looks like it may be a productid, but without better views, that is about all I can say. 

 

Pictures of the fossil from directly above, and from the bottom would be more helpful.

Example:

Why do you say it is in granite?

Definitely not granite - looks to me like limestone or dolostone.

Looks like limestone to me. I have similar rocks locally, a black limestone. The dark color suggests an organic rich environment, which I believe means low oxygen.

 

That brachiopod likely was buried in sediment at the bottom of a warm shallow sea.

Not sure why I wrote that ; ) Took another look at what is usually found in that area and Limestone/Dolostone would indeed be the closest match. Thanks

I figured it was an aberration!
