LiDAR Reveals 478 Olmec and Maya Ceremonial Complexes in Mexico

Oct 26, 2021 by News Staff

Using a revolutionary technology known as LiDAR (laser imaging, detection and ranging), an international team of archaeologists has discovered 478 rectangular and square complexes, probably dating from 1050 BCE to 400 BCE, in the Olmec region and the western Maya lowlands of Mexico. The LiDAR data have also revealed that the earlier Olmec center of San Lorenzo had a central rectangular space, which possibly provided the template for later sites. Ancient...
