The big one looks like Glycymeris , but the barnacles and especially the spiny bivalve inside are wonderful! :wub:

 Nice, I like the little spiny one!

Wow lovely and what a surprise. I agree it looks like a glycymeris.

I don't know for the others but I like the spiny one!

Nice specimen!

 

Inside Glycymeris sp. it looks Acanthocardia aculeata (LINNAEUS, 1758).

 

Best regards,

Very nice surprise. Are the round marks on both the outer and inner surfaces of the big shell bore holes? Do they go completely through the shell? Most shells may have one if fed on by a gastropod. Maybe these are post mortem but by what organism? In my limited experience, it does not look like a boring sponge marks. What is the story this shell tells us? Would be interested on anyone's thoughts. Thanks

I think the holes are made post mortem

Hi,

 

Very nice fossils ! Do you have an age old more precise than Pliocene ? Basal, middle, upper ?
