Local people discovered a collection of rock carvings on top of the Cerro de Peña, a mountain in central Mexico. In total archaeologists found two etched stone panels and a number of smaller carved stones. The carvings cover 87 glyphs, a male human figure with horns and a loincloth, a female figure resembling a bat, an iguana, and an eagle.
The carvings are thought to be Zapotec who lived in the area starting 2,500 years ago. They were known to use glyphs and had a sophisticated architectural style.
