(Our happy hour fact to amaze your drinking buddies with.)

Carcharodon Megalodon, an ancestor of the great white shark had at least three times the biting power of the Tyrannosaurus rex.

The Megalodon has been extinct for more than 1.5 million years, but in its day it was a 50-foot long, 100-ton killing machine that fed on whales by ripping off their tales and flippers. Researchers were able to recreate the ancient sea beast's bite by using sophisticated 3-D digital models built from X-rays of a modern great white.

While the Megalodon is now considered to have had the all-time most forceful jaw, much of that has to do with its gigantic size. In fact, according to researcher Stephen Wroe, "Pound for pound, your common house cat can bite down harder."

Good to know. Now when we have a non-screwtop bottle and no opener, we'll grab the cat.
