Archeologists from Mexico's National Institute of Anthropology and History (INAH) reported finding the largest-ever body of mammoth remains.
Diego Prieto Hernández, director of the institute, said the discovery "represents a watershed, a turning point in what we until now imagined to be the interaction between hunter-gatherers with these huge herbivores". They were uncovered in pits measuring six feet deep and 25 yards in diameter in Tultepec.
The discovery site, called "Tultepec II" has been under excavation for 10 months. Experts say the remains correspond to at least 14 individual mammoths.
Anthropologists in Mexico have unearthed ancient pits used to trap mammoths.

Groups of 20-30 hunters would use torches and sticks to separate a mammoth from its family and push it into the traps. The holes housed hundreds of 15,000-year-old mammoth bones, leading scientists to deduce that they were purposefully ensnared in the quarry. According to CNN's Guy, the bones of one mammoth were arranged in "symbolic formation", and intriguingly, one of the bones showed signs of a healed fracture.
Speaking to CNN Luis Cordoba, an INAH archeologist, said: "They must have considered it fearless and ferocious, showing their respect with this particular arrangement". Researchers found approximately 800 bones in the two pits, along with the remains of a few horses and camels.
Further research is needed to determine whether there are more mammoth traps nearby.
