Divers in a Mexican cave found something pretty incredible nearly 200 feet below sea level: the skeletal remains of predators from the Ice Age that died somewhere around 11,000 years ago.
The cave, called Hoyo Negro, is located in the Yucatan Peninsula. Since the climate there is generally too warm for things to stick around for very long, most of Mexico and Central America don’t hold a whole lot of geographical evidence. But since this particular cave acted as a temperature trap, it holds a wealth of information that comes in the form of skeletons of creatures unlucky enough to plummet to their deaths. One of them, in fact, is Naia, a teenage girl who died at the age of 17, around 13,000 years ago. She is the oldest complete skeleton ever found in the Americas. Also included in the extraordinarily deep grave are “saber-toothed tigers, cougars, tapirs, ground sloths, and elephant-like gomphotheres,” among other things.
