3, maybe exogyra ?

6 and 7 pectinides

9 neitheas ?

10 and 11, on the left and the center inoceramus ?

16 ostreas

17 to 20, maybe rudists ?

Hi fifbrindacier :D !

Unless the rocks were brought for a natural process (such as glacial action), you can't have neither exogyra sp. (Jurassic to Cretaceous), nor inoceramus sp., nor rudists (Upper Jurassic-Cretaceous),I think (if I'm wrong feel free to correct me :) ).

Beautiful bivalves :wub::drool: !

IMO (please take these as proposals for discussion and not as very probable Id's :fistbump: ):

1-Veneridae family.

2-other pic would help, but couldn't that be a crab?

3-other pic would help (some type of oyster, maybe)

4/5-I'm not sure...Perhaps veneridae.

7-wild guess:Spondylidae???

10-Veneroida order (maybe veneridae family).

12/15-Burrows ??? (bioturbation).

16/17-oysters (a bit hard to determine,I think).
