"Many of the excavated blades are made of obsidian which the archaeologists have traced to a source hundreds of miles away in the Mexican highlands. They believe the spears belonged to warriors from Teotihuacan, an ancient civilization near Mexico City and an ally of Tikal, which was an enemy city of El Mirador."We've found over 200 of the obsidian tips alone, as well as flint ones, indicating there was a tremendous battle," said excavation leader Richard Hansen, a senior scientist in Idaho State University's anthropology department who is pushing the pyramid battle theory."

"Hansen's archaeologists found graffiti they believe was left by Teotihuacan fighters who smashed up carved Maya monoliths and left crudely etched skull drawings, known as Tlalocs, on the rock as proof of their victory.
"The Tlaloc is the war god image of the highland Mexicans (and we found it) crudely pecked on these monuments, suggesting that perhaps a hostile event had taken place here," Hansen said."
