Not sure if that pedicle looks quite correct. Would have to get the hide off!! Lol. I Get a lot more elk in with broken pedicle but a fair amount of deer too. Usually are not real apparent until you can see the skull. Gravity must affect the antlers like it does a tree, as they always attempt to grow up and back to normal.
My theory is they break the pedicle when spikes, then when they lose the antlers and start to grow new, the bone attaches what ever direction it's pointed. The antler growth is the fastest growing bone known. Other possibility is an injury to one of his legs which will affect antler growth.
Really enjoy your Pics. Fantastic reference material.
Thanks
