Ten years ago I found a skull (I then thought it was a bird's) on the beach in western Turkey. Now I'm curious what it actually is. I was thinking you might help me in specifying the species. By the way I'm a total layman concerning biology.

The numbers in the attachment are milimeters

Thanks in advance.

Kind regards,

Hasan Can
