It looks like a part of an animal skull, eewwww.Si
It is -- a deer skull. Some dog or something left it in the yard. I soaked it in bleach and let it dry in the sun. Since the photo show is over now -- I am hoping to get caught up on my commenting!!!!
Interesting shot Donna, so is that zig zag a part of the actual skull? Si, it's only a skull! lol
The zigzag is the part of the skull -- they are called sutures.
