The 15,000-year-old Mexican mammoth trap.

ABC News (Australia) shares the findings of a Mexican expedition that has discovered a trove of mammoth bones in what appears to have been a pair of pits dug by humans to be prehistoric mammoth traps:

Archaeologists have said they have made the largest discovery of mammoth remains, with a trove of 800 bones from at least 14 of the extinct giants found in central Mexico.

Researchers from Mexico’s National Institute of Anthropology and History said on Wednesday (local time) the pits were found during excavations on land that was to be used as a garbage dump.

The pits were about 1.7 metres deep and 25 metres in diameter.

The institute said hunters may have chased mammoths into the traps. Remains of two other species that disappeared in the Americas — a horse and a camel — were also found.

The skeletal remains were found in Tultepec, near the site where President Andres Manuel Lopez Obrador’s Government is building a new airport for Mexico City.
