Archaeologists using billions of LIDAR shots at the ground in the Puuc region of the Yucatan have found extensive Maya structures including artificial reservoirs, 1,200 ovens, farming terraces, 8,000 housing platforms, each house having 2-3 rooms. Four large acropolises dating from 700 BCE-450 BCE, civic centers built from 600-750 CE in very distinct city layouts not seen elsewhere. Elite housing was dispersed throughout, and not concentrated. No defensive structures exist. This looks like a very large peaceful community.
They built cisterns to collect rainwater in their limestone terrain, and aqueducts with long channels. They had a widespread stone working industry with quarries and 1,232 circular ovens to heat sandstone to produce lime for mortar and to soften maize for help with nutrients.
The study was published online Wednesday (April 28) in the journal PLOS One.
