Guatemala Mayan city may have ended in pyramid battle

EL MIRADOR, Guatemala (Reuters) - One of Guatemala's greatest ancient Mayan cities may have died out in a bloody battle atop a huge pyramid between a royal family and invaders from hundreds of miles away, archaeologists say.

Researchers are carrying out DNA tests on blood samples from hundreds of spear tips and arrowheads dug up with bone fragments and smashed pottery at the summit of the El Tigre pyramid in the Mayan city of El Mirador, buried beneath jungle vegetation 8 km from Guatemala's border with Mexico.

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.

"It looks like this was the final point of defense for a small group of inhabitants," told Reuters.

El Mirador is one of the biggest ancient cities in the Western Hemisphere and is thought to have been home to between 100,000 and 200,000 people at its height. Historians believe it was built up from around 850 BC and flourished for hundreds of years before it was mysteriously abandoned in 150 AD.

Many archaeologists think the size and elaborate stucco decoration of the buildings in the city are to blame as the inhabitants used up stone, trees and lime plaster in their construction until their resources were entirely depleted.

Hansen's team believes a group of some 200 people, thought to be the last remnants of the royal family, stayed in the ruined metropolis until they were attacked by warriors from Teotihuacan.
