There was a time in China, around 2,300 years ago, when people of high status were entombed in crypts that would also contain the bodies of exotic animals and domestic livestock. Animals such as leopards, lynx, black bears, and cranes, among others, have been found in these tombs. Archaeologists working on a set of 12 burial pits were surprised to discover the remains of an unknown and extinct type of ape inside one of them.
