Oyster from Wroclaw

Hey everyone,

Someone on reddit posted this great-looking oyster, asking for ID. And I can’t figure it out. The hinge looks really weird to me and inconsistent with the usual Ostrea oysters I see...

They said it was excavated from a construction site about 12 years ago in the city of Wroclaw (Poland), near the Odra/Oder River. Which means there isn’t any literature about the age/formation/etc. Only thing I could find is this geological map that puts the area in Tertiary sediments (which is logical but not very helpful).

Anyone have an idea of what to say about this shell? Age and formation would be great, and genus (or species but I’m not getting my hopes up that high) also. 

Maybe @Kasia you’ve come across some of them? 

Thanks in advance!

Hi Max,

it could be for instance Plagiostoma clam https://www.steinkern.de/steinkern-de-galerie/sonstige-fundstellen-mitteltrias/plagiostoma-lineatum-14212.htmlhttps://en.wikipedia.org/wiki/Plagiostoma_(bivalve)http://paleopolis.rediris.es/cg/1610/index.html

or Panopaea clam, or some kind of Inoceramid (see Inoceramid stratigraphy of the Turonian and Coniacian strata in the environs of Opole
(Southern Poland) at acta geologlca polonica.

 

I hope it helps with ID.

 

Regards,

 

Kasia

Thanks for the help Kasia, but unfortunately I don't think any of the genera you proposed fit the shell in OP...
