NEW ORLEANS, LOUISIANA—The Maya site of La Corona in Guatemala was part of a Classic-era kingdom ranging from southern Mexico to Central America, according to a Science News report. Marcello Canuto of Tulane University and Tomás Barrientos of the University of the Valley of Guatemala reviewed lidar mapping of the Guatemalan lowlands, excavation data, and studies of Maya hieroglyphics, and found that the remote city of La Corona was ruled by the Kaanul rulers, or Snake Kings, who were based in Mexico at the city of Calakmul. La Corona may have served as a relay center for precious goods traveling in and out of the Kaanul capital to sites further south. “Our work supports the idea that the ancient Maya formed interconnected political systems, not largely separate city-states as traditionally thought,” Canuto said.
