Devonian brachiopod? From Resteigne

[Max-fossils]

Hi all,

 

During my trip to the quarry of Resteigne, 

I namely found this brachiopod. Is this a Sieberella sp (as proposed by Roger @Ludwigia)?

Because the fact that it is asymmetrical makes me want to incline to bivalve... But I'm not sure what kind of bivalve it would be then.

 

Location info:

Resteigne quarry, Belgium

Jemelle Formation (mostly)

Eifelian, middle Devonian; ~ 390 mya 

 

Thanks in advance for your replies!

(On this last picture, the part on top looks like an asymmetric umbo of a bivalve... But I'm not sure.)

Yes, that is a Sieberella with the characteristic ribbing at the center.

+1 for Sieberella.
