Would these be good for taxidermy?

I've been looking around for some animal skins for taxidermy and came across these beautiful coyote skins for a great price. Now the problem is that I'm not sure if they'd work for taxidermy.

If you look at the fourth image it's suggested that these skins have been mounted before but by a really good taxidermist. So should I take the chance and buy one to save money or just spend more on a pelt that's tanned specifically for taxidermy?

I'm kind of on a budget which is why I'm tempted to buy this instead.
