The discovery of a new tomb at Teotihuacan's Pyramid of the Moon has provided critical evidence for reconstructing the city's 2,000-year-old history. The tomb contains human skeletons, animal bones, and offerings that differ from previous discoveries, suggesting a significant cultural shift between two phases of pyramid construction.
A psychologist proposes that cave artists, who painted sophisticated images 31,000 years ago, were actually people with underdeveloped minds. An autistic girl's unusual drawing skills inspired this theory, which suggests that artistic talents emerged due to mental deficiencies rather than sophistication.
A recent excavation at the Pyramid of the Moon in Teotihuacan has uncovered a skeleton and 150 surrounding artifacts dating back to approximately 100 A.D. The burial is suspected to have belonged to one of the city's rulers, providing critical information that could revolutionize modern understanding of Teotihuacan's culture and history.
A team of archaeologists has discovered a previously unknown mound complex in Louisiana built between 5,000 and 5,400 years ago. The site, Watson Break, consists of 11 mounds that predate other known complexes by 1,900 years and provide clues about the planned engineering behind their construction.
The discovery of an ancient Peruvian obsidian quarry provides evidence for long-distance trade in the Americas as far back as 2,500 B.C. The quarry, found by University of Wisconsin-Madison geographer Sarah Osgood Brooks, contains nearly 75% of artifacts identified as coming from a single source.
Researchers analyzed obsidian blades from workshops in Mexico, finding that the number and type of mistakes made can indicate a craftsman's level of skill. By ranking workshops according to their aggregate skill, archaeologists can better understand the economic complexity of ancient societies.
