Mummies Don't Scream

As this mummy from the ancient Chachapoyas civilization in Peru shows, mummies died screaming.

Or at least that's what I thought!

But then I read this article which states that it's all about the mummy's jaw. If it isn't wired shut, “the jaw will drop down as the muscles relax and decompose after rigor mortis.”

And with an open mouth, that means we have one screaming mummy, coming up!
