A lithic CAST of an authentic obsidian atlatl dart point, from the Teotihuacan Cultural Complex of Mesoamerica. The artifact comes from the Dr. Allan Heflin collection, from work in the area west of Lake Sayula in the valley of Mexico from the 1940's to 1970s. The culture is most famous for its pyramids and city complex in the valley of Mexico, but it had much larger expanse of influence in Central America, which started around 200BC and lasted until around 700AD. It was the largest urban center of Mesoamerica before the Aztecs, with a possible population of over 150,000 at its peak.  The political/religious structure is still under much debate, as rulers are not clearly depicted in the art as they are in Mayan architecture.  One of the ideas is that the Teotihuacan complex was a major center for merchants and art distribution, with the raw material of Obsidian as a main commodity. This fine example of an obsidian point would have been the size to fit an atlatl dart/spear, at 60mm long, 31mm wide, and 7mm thick. This point shows slight usewear in the hafting region, and also a possible impact fracture at the tip, which did not destroy the point, as it was resharpened around it to bring it back into shape.
