About 1,400 years ago, the ancient Maya city of Uxul thrived in Mexico. Located in a densely populated area between the larger cities of El Mirador to the south and Calakmul to the northeast, Uxul had trade connections that stretched as far south as modern day Guatemala. Now, archaeologists have uncovered something dark about this ancient city. It turns out that the Maya decapitated their enemies before shoving them into a mass grave.
For the past five years, archaeologists have been excavating the historical city of Uxul. Now, they've uncovered the skeletons of 24 people in an approximately 32 square meter artificial cave that was formerly used as a water reservoir.
