Does anyone know whether or not the skulls of predators such as lions or bears are much thicker than those of humans? For example; could a lion or a bear survive a well-placed blow to the head from an aluminum baseball bat? I know such a bat could crush a human skull like a watermelon, but would the same apply to most predators? Assuming you could avoid the claws, could you kill or at least incapacitate a lion or grizzly with a bat?

I'd guess these animals are "built tough" including thicker skulls for a couple reasons, including living as they do in the wild, and their jaws are major implements requiring tougher jaws and more muscle. Also keep in mind that they have smaller brains than humans, so it's literally a tougher nut to crack.

 

I would also guess that, depending on the temperament of the animal, a line drive to the head with an aluminum bat might make it think twice. Better yet, instead of aluminum, you might want to use something made out of "stihl"
