European cretaceous deer heart clam ?

[Quer]

Hi,

From time to time I found in Upper Campanian strata of SE Pyrenees some big steinkerns looking much like the American "Deer heart clams".

 

So, my initial guesses are genus Cucullaea/Pholadomya/Arca, especially Cucullaea/Pholadomya royana, but my knowledge of bivalves other than rudists is very limited. Can anybody help? @Ludwigia @fifbrindacier

 

Size of the biggest are 92 x 80 x 68 mm

 

 

Center one is the best preserved (75 x 67 x 53 mm) :

 

is

 

Finally a different, smaller, specimen from same area and strata. I have no guess about it:

I think the last one is a kind of Cardia

Sorry I can't help you this time, since I'm not so familiar with Cretaceous bivalves.

Thanks, anyway.

This is the bivalve that you are looking for.

Thanks, Creek-Don for this interesting ancient topic about the issue.

For steinkerns I'd recommend the Cretaceous Fossils of New Jersey two volume set by Horace Richards. You can get a pdf by googling. I suspect the Campanian genera from New Jersey and your area are quite similar.
