RE: Extra antler or another deer's antler?
Looks like a third pedicle forming the the base of the eye socket. The end of the antler is split and covered in velvet, not skin. No fur. No pedicle on the end. Doen't have the look of a mainbeam at all. Where are the burs at the base? Where is the G1/brow tine? It is a classic look of a abnormal drop tine covered in old velvet at the tip. The eye is obviously affected by how large the pedicle has become.Thecoatis muchlighter surrounding the pedicle just as it is around the rest of the both eyes. It wouldn't be lighter from an injury.
