What could this be?

[Pedra]

Hi!
Could you help me with this piece? I\'m not even sure about it being a fossil. If tt were, could it be some kind of fish piecemouth?
(North east Spain, middle/upper Eocen)

Thanks in advance.

Hi Pedra,

Looks to me like a piece/fragment of an oyster
Which kind i don\'t know.

So if i had to put an name on the tag it would be: Ostrea sp.

greetings,

Charles

Hi KarelS,
Ups! I\'ve just seen I had forgotten to thank you for your comments. I agree with you that it must be part of an oyster. It\'s just that I wished it were something a bit more exotic.
