In the south of mexico, archaeologists have discovered the oldest and at the same time the largest monumental complex of the maya known to date.
Three years ago, the team around takeshi inomata from the university of arizona registered conspicuous structures in tabasco using the so-called lidar method. Lasers from airplanes scan the ground and reveal buildings under the vegetation.
In all, the researchers discovered 21 larger and smaller ceremonial centers in the region, almost all of them similar in design: a rectangular plateau running in a north-south direction with a series of earthen mounds.
