WASHINGTON (AP) — As if the largest bug to ever live – a monster nearly 9 feet long with as many as 64 legs – wasn’t terrifying enough, scientists could only just imagine what the extinct beast’s head looked like.

That’s because many of the fossils of these creatures are headless shells that were left behind when they molted, squirming out of their exoskeletons through the head opening as they grew ever bigger — up to 8 to 9 feet (2.6 meters) and more than 100 pounds (50 kilograms).
