I've only used maceration and natural decay, which is unpleasant and messy.

And for the record, I personally prefer my animals alive over dead. I'm not a fan of trophy hunting really. Hunting to eat, playing by the rules, I have no problem with. But killing just to kill is putting unnecessary pressure on wildlife, just to hang it on your wall. I am not a fan off that thought process. Not trying to make a debate, just thought I needed to say that here.

Most the skulls I have acquired were either found or processed from road kill. I will admit though that I have a few that I acquired when I was younger that were likely a result of hunting. I try to stay away from that industry nowadays though. Not trying to start a debate, just don't want my stance confused. I only shoot animals with my Nikon.

For the record, I have nothing against hunters who respect the land, the animals and the law. Its the poachers and idiots who kill just to kill that urk me.

Anyway, skulls are cool. A few years back I bought a human specimen from the Bone Room in Berkeley. I would like to acquire another.
