Archaeologists have unearthed two ancient Mayan cities hidden for centuries in thick vegetation in the heart of the Yucatan peninsula.
Aerial photographs helped the researchers locate the sites in the southeastern part of Mexico’s Campeche state, near a large Mayan site discovered last year by the same team.
No other site has been found in this 1,800-square-mile area between the Rio Bec and Chenes regions.
One of the newly discovered sites features an extraordinary façade with an entrance that resembles the open jaws of an earth monster, reported Discovery News.
American archaeologists documented the façade and other stone monuments in the 1970s, although their drawings have never been published.
