We've all seen those National Geographic specials in which a pack of fleet, deadly cheetahs massacres a clueless herd of wildebeest. As dangerous as they are, though, those cheetahs would be bite-sized hors d'oeuvres for the much bigger, deadlier (and, yes) dumber mammals of the Cenozoic Era, which ranged from plus-sized rhinoceroses, pigs, hyenas and bears to giant whales and saber-toothed cats. Here, for your delectation, is our list of the 10 deadliest mammals of the Cenozoic Era, with one ancient Cretaceous furball thrown in just for fun.
