Yup, that is the horse skull. It looks a bit fragile and may not be in in good shape, lets see what the thaw brings...Some of the teeth fell out of the Javelina skull, but they are all in the wheel barrow. Some clear hot glue, a little time and you'll have a secure complete set of choppers. Let the snow melt a bit and you can all if it. No lower jaws? I'll send ya all the teeth so if a tooth is missing on top and you can glue one in that fits, it might look better.
The coon skull is frozen with meat still on/in it. Might even have a woodchuck skull too. From this seasons trapping/shooting. Was gonna try using an ant hill this spring to clean them off for me.
This is how we display some of the smaller skulls in my son Joes room. I stained a CD storage rack. Just an idea.
