A 1,400-year-old scorpion-shaped effigy mound, discovered in the Tehuacán Valley, might have served as an astronomical observatory, researchers say.
The mound is strategically placed in the center of the largest preserved prehistoric irrigation system in Mesoamerica, comprising approximately 100 square kilometers of canals that have functioned continuously for more than 4,000 years.
The discovery has been described as “unprecedented”.
