I Never saw it when finished, but by the time the taxidermist had removed the skin and horns from the massive old skull and remounted it on what every it is they use to stretch the skin over, I'm sure it would have been lot lighter., but still a fist full.
I could imagine it would still have some weight to it. I think they use a foam type core which is high density. Still after a few minutes of holding it up you would feel it.
Just found out some info: The link points to a mount that weights 35 lbs.
Bison are really boney. A 2 yr old weighs near a ton. On the hooks, I'll guess 600-700lbs. In the freezer, 450-550lbs.
Bison skulls are built like house roofs = top and bottom flat surfaces and a 1" space filled with all kinds of boney rafters.
I don't believe for a minute that any carving of a bison would need to reflect photographic accuracy.
Get the big masses mostly right and the viewer's mind will do the rest.
When I was 8 years old I was nearly killed by a charging Bison. My dad took me to a zoo. They were closed but we saw that we could get to the bison enclosure.
Luckily there was a chain linked fence between me and one ticked off snort'n , snot flying ,head ramming beast. I ran up to the already bowed out fence where he has hit it many times...I didn't notice the damaged fence when I ran up. I bet he hit it doing 30mph and I was running about the same away. My dad was running to me and saw the whole scene. He was happy I was alive and may have said " we don't need to tell your mother about this."
I can believe that, GG. Bison are extremely unpleasant. Given the opportunity, they will stomp and gore you to a pulp, just for fun. They are not dumb-arse cattle.
Many stories of close calls here, won't waste space with them. The rancher would rather face off with a Grizzly bear.
But, under my knife and fork, they are heavenly food.
