Ten human skeletons were discovered buried on their sides in a spiral circle with their arms intertwined in Mexico.
The 2400-year-old remains were found in Tlalpan, the largest borough of the Federal District of Mexico City. The remains were found 1,5 meters below the Pontifical University of Mexico and are the largest collection of skeletons from the Mayan Preclassic period (1000 BCE-250 CE) ever found in the Basin or Valley of Mexico.
One of the skeletons has been adult in the time of death, but there were also a 3-year-old infant and a one-month-old baby. The rest were teens or young adult.
It was a circular, interlocking burial and some of the skulls showed signs of intentional deformation along with dental mutilations. While the cause of death remains unclear, their careful positioning suggests a mysterious ritualistic component to the burial.
