National Geographic Clash of the Americas: It may have been one of the most cataclysmic geologic events of the last 60 million years which shaped America as we know it today. The narrow, 400-mile-long Isthmus of Panama, once buried below the sea, rose up and connected North and South America. This new land bridge unleashed an astonishing animal encounter: Prehistoric predators and prey - each unique to their worlds - came face-to-face for the first time. An armor-plated ancestor of the armadillo. A saber-toothed marsupial. A horse-like creature with three-toed feet. Evolutionary history changed forever as animals from the continents clashed.
