Sure, that sounds like a relatively easy way to kill an elephant, but 3 days of waste leaking into the body cavity causing infection is basically fouling the meat before you can butcher it, isn’t it?
It's amazing what cooking plus a hardened gut can deal with. If my dog finds a kill, she happily consumes meat older than that without cooking at all. Pretty amusing to see her so happy with a stinking floppy leg hanging from her mouth by its ligaments.
Clovis man couldn't afford to be picky. Survival was everything.
