All other horned creatures have a clear "root" like transition where the horns are attached to the skull. Also are the horns normaly a
different color then the skull itself.
Horns are made of the same thing hair is made of, wich is not the same material our skulls and bones are made of.
This skull however has no root like transit from skull to horn and the material of the skull and the horns look exactly alike.
An astute observation. I concur, and I've drawn literally a TON of cow skulls in my day (while in art class, they were an often used object for
still lifes...) You REALLY notice detail like this when you draw them OVER and OVER again, hehe....
