Please help with skull identification
 

Howdy y'all,
I was wondering if you could please help me to identify these skulls that I found in my cat's outdoor house today. I'm not positive that they are skulls, but I just guessed that because it looks like they have eye sockets and nasal openings on the sides. Plus I have no idea what bone it might be if it's not a skull.

That styrofoam plate is a standard sized 8" plate.







I'm in IL near Chicago. Thanks! :)

They appear to be hip sockets from some kind of bird.. Prolly chicken left over from someones roast.. I do not believe they are any form of skulls anyways.. If you look at the ones showing the underneath of them you can see where the back bone starts..

possible breast bone out of a bird?.......

It's a chicken pelvis.



I've broiled a few birds in my day...

Mystery solved I guess.....

I do not believe they are any form of skulls anyways.

lol i feel stupid... i was gonna say beaver XD

Pelvis
 

These are pelvis and sacrum bones of a bird. Tis is certain.
