Mexican Mammoth Traps

Mexican archaeologists recently announced their discovery of two mammoth traps, where wholly mammoths could be herded then killed once trapped. Most importantly, the pits have been dated to 15,000 years ago. That makes them the oldest  evidence of prehistoric hunting pits in the Americas.

The two pits contained about 824 bones from at least 14 mammoths. And one of the skulls found had marks of a spear wound on the front, suggesting that hunters were actively attacking the large mammoths.
