Researchers have found a “graveyard” of about 60 mammoths ahead of the construction of an airport just outside Mexico City, according to the National Institute of Anthropology and History (INAH) in Mexico.

In addition to the ice age findings, researchers at the airport-construction site uncovered remains from an entirely different time period — pre-Hispanic times, when 15 humans were buried there, the INAH reported.
