Its not a skull , It the breast plate. Was hoping it was a cat but to small...but seriously not sure what kind of animal . I am gonna say
turkey....the extra bone is a scapula corcoid.
I don't think it's a skull either, it looks more like the pelvic region of a bird. The two holes in the third picture are where the legs would have
been attached. Below are two pics of identified bird pelvises. I don't know what kind of bird though.
It is a sacrum-coccyx of some animal. Looks like a bird. The other "U-shaped bone" is a "pully bone" my grandmother would say. She would cut
the pully bone away from the breast of the chicken before she would cook them. After you would eat the pully bone, you would pull the bone from
either side with your brother or sister and the one with the short side would get a wish. AKA - wishbone.
ahhhh, thanks for shedding light on the subject. All I know about the pics is what's stated in the Craigslist post, they're not my pictures. I've
been looking over pictures over the internet and haven't found a match.
P.S. this was posted in the Columbia, SC Craigslist.
I would almost go with vulture pelvis bone and wish bone from between the wings. The picture seems to come from Columbia South Carolina from the
craigs list posting.

It's indeed a bird's pelvis (aka pelvis girdle). It would have been easier to identify if there was a scale of some sorts (the lamp we see in the
corner) may indicate that it's a smallish bird.
The pubis bone, rib(s) and pygostyle which are missing (or not visible?) in the image could (have) help(ed) to narrow down the search.
For example a ground-living bird's bone structure differ from that of swimmers and birds of pray on the other hand have very complex and thick bone
structures.
