Perna-Shell of Albena, Bulgaria? - Herner - 07-25-2012
Hi,
I found this shell on the beach of albena.
they are certainly very heavily worn.
Possibly Perna or heavily eroded shells of Crassostrea gigas?
Size: 39,5 x 12,5 x 4,4 mm
I also found there are similarly shaped shells, but they were light brown or white.
Greetings Herner

...and here are more individuals of the same species:

It is quite similar to the Mediterranean Perna perna, but I can't say for sure if it is that species. It is not a Crassostrea.

hello Paul,
..I am in despair!
On the site there were very many of these mussel shells.
there flows into the sea a river, so it is brackish.
Maybe it's not a sea shell, but a freshwater mussel?

Looks to me like a very worn Mytilus.

Hi,
perhaps a very worn Mytilaster or Modiolus phaseolinus?
The shell is not so fragile as the Mytilus species.
It is relatively hard.
