I found this skull whilst digging a latrine in Oman. I think it might be from a Turtle but gateful for a more positive ID.
Changed Group to Fish as suggested.

It doesn't look like a turtle skull. I think more like a fish. Maybe you could try changing the category to fish using the edit tab, you might get an answer there.
