Archaeologists Find Oldest Known Mayan Calendar 185
sciencehabit writes "A team of American researchers has discovered a small trove of ancient Mayan texts in a surprising place. In a paper published online today in Science, researchers report finding Mayan astronomical tables and other texts painted and incised on the walls of a 1200-year-old residential building at the site of Xultún in Guatemala. The newly discovered astronomical tables are at least 500 years older than those preserved in the Maya codices, giving researchers a new glimpse of science at the height of the Maya civilization. 'I think we are all astonished by this find,' says Stephen Houston, an archaeologist at Brown University who was not part of the team."
