not all too uncommon for some of our "half racks" to have busted skulls like that. but, that ones seems to have a good bit of bone missing...

may or may not be alive..

i never seen one of the half racks up close...just their skulls boiled out and can definently see that they were half racks because it was busted off the skull....dont know if it would ever grow back an antler there again with part of the skull missing...
