NUEVO LEÓN, MEXICO—Prensa Latina reports that archaeologist Araceli Rivera of Mexico’s National Institute of Anthropology and History (INAH) has found animal remains that may have been used in rituals some 8,000 years ago. The remains include the teeth, long bones, skulls, ribs, and vertebrae of mammoths, camels, horses, llamas, and prehistoric bison. The bones had been placed in a rock shelter and covered with a rectangular stone that researchers have dubbed La Boveda, or The Vault. The researchers think The Vault may have been illuminated during the winter solstice, at a time when food may have been scarce. For more, go to “Under Mexico City.”
