Greek fossils!

[PetrosTrilobite]

Not only these are the firsts greek fossils in my collection, but are the only fossils that i have found. I found the fossils in Pikermi - Rafina, Attica (nearly Athens). Total over 4-5 kg (or over 20 specimens). I will post some of these. A huge clam, a vertebra, and some... i don't have idea. Age Pliocene or Miocene. Any help with the ID?

These look like barnacles.

Nice! The most hard is to find ID for the vertebra...

No idea. Can't be within the same deposit.

Pecten, same association as above, missing the handbook for exact species.
Lobes seem symmetrical, thus I think is Pecten sp.
Once the Greek border opens again, I will zap to Athens to have back my book!

 

Nice research here

Indeed, as @PetrosTrilobite said, it'll be extremely difficult to identify a vertebral fragment, especially since we only have a single face of the centrum. For proper identification of a vertebra, you need at least both faces, views from ventral and - sometimes - dorsal sides, and frequently the neutral arch as well. As such, I don't think this specimen can be identified...

 

The shell on the other hand is probably some species of Pecten.
