I found this bone in a forest preserve in Chicago. i would normally have thought it to be a deer jaw bone, however it is very wide. sadly, it is only a fragment and is not complete so i cant identify it myself. the teeth kind of imply a hoofed animal. i woulld appreciate if somebody would let me know what they think it is. top view.
this would be the side that is outside of the mouth
this would be the side that is inside the mouth
this is the bottom of the whole fragment where the teeth go down into the jaw
This is the part of the skull which holds the upper teeth in a hoofed animal. The tooth closest to the back of the mouth has not come through yet so this is a young animal. In young animals the individual bones of the skull are not fused together and the skulls can come apart during decay, just like this one has,
