PhD student finds lost city in Mexico jungle by accident

An ancient Maya city has been found “hidden in plain sight” beneath the jungle canopy in the Mexican state of Campeche. Archaeologists used a laser technique called LiDAR to scan the area, “accidentally” discovering the forgotten complex, which contains pyramids, amphitheatres and sports fields. They think the site, which they’ve named Valeriana, might have housed up to 50,000 people, which supports claims that Maya lived in complex cities or towns, not in isolated villages.
