So.  Megalodon Sharks were big enough to, if they were so inclined, eat a Tyrannosaurus Rex with little or no chewing.  They didn't eat T. Rex, instead choosing to feast on whales.

I am so glad these things went extinct.  I don't say things like that often, but if those guys were still swimming the oceans, I'd be living in Kentucky.  Just sayin'.
