Mexico’s human history agency says another ancient Mayan city has been discovered in forests in the southern part of the country. The country's anthropology organization INAH announced the discovery recently. INAH said the newly discovered city includes large pyramid-like buildings, stone columns and other structures placed in circles. The agency named the city Ocomtun - meaning stone column in the Yucatec Maya language. It would have been an important center between 1750 and 1000 years ago. The ancient city is in the Balamku ecological reserve on the country's Yucatan Peninsula. It was discovered during a search of a largely unexplored area that is larger than the country of Luxembourg. The search took place between March and June using aerial laser mapping (LiDAR) technology.
