A mammoth graveyard: 60 pachyderm skeletons discovered together in Mexico

While building a new airport, construction crews uncover a gigantic collection of ancient bones.

  • During digging for a new airport in Mexico, workers came across three sites containing the remains of mammoths, as well as some pre-Spanish human burial sites.
  • It's unclear why the mammoths were all found in this one spot, though it may have to do with an ancient lake.
  • Retrieving this massive sample will likely give experts new insights into a long-lost North American pachyderm.

In the Mexico Basin about 45 miles north of Mexico City in the Santa Lucía region, the new Felipe Ángeles Airport is under construction. According to Mexico's National Institute of Anthropology and History (INAH), workers there have dug up a massive surprise: a trove of 60 ice-age mammoth skeletons. They've also unearthed 15 pre-Hispanic human burial sites.

The pachyderm bones belong to Colombian mammoths, Mammuthus columbi, who last lived in North America in the Pleistocene epoch between 2.6 million and 13,000 years ago, when they are believed to have become extinct. They're the mammoths that visitors to Los Angeles' La Brea Tar Pits encounter. (No woolly mammoth remains were found in Santa Lucía.)

It's not yet known how many of the mammoth skeletons are complete. It is clear, though, that males, females, and their young are there. The bones are being found between 80 centimeters and 2.5 meters below the surface and spread across three exploration areas. First discovered in October 2019, the digs are still being stabilized and undergoing analysis and classification, according to INAH National Coordinator of Archaeology, Pedro Francisco Sánchez Nava.

How 60 mammoths wound up together in death at this location is an interesting question. No signs of human tracks leading to or from the site are evident nor have any indications of hunter accommodations have been found. By contrast, the prehistoric mammoth hunting site discovered in the Mexican municipality of Tultepec in November 2019 does exhibit such signs of human interaction.

Archaeologists suspect the 60 mammoths got stuck in a muddy swamp over time — the site is near the shores of the former Lake Xaltocan. Researchers say the most complete skeletons found are those close to the former lake's shoreline. It remains possible that the immobilized mammoths were then preyed upon by hunters even without clear evidence of that so far.

Once the remains are retrieved, they'll be studied by a team of 30 archaeologists, supported by a trio of restorers, to make a full account of what's been found. They hope to learn more about how and precisely when the animals lived, ate, and what health issues they may have had as evidenced in their skeletal remains.

Meanwhile, construction of the new airport continues. Says Salvador Pulido Méndez, director of INAH Archaeological Salvage, "So far, no findings have been recorded on the land that lead to the rethinking of the construction site, either totally or partially. Rather, the works have allowed INAH a research conjuncture in a space where, although it was known of the existence of skeletal remains, they had not had the opportunity to locate, recover and study them."

Prior to the beginning of construction, the Santa Lucía region had been used by the Santa Lucía Military Air Base, and the national defense organization Sedena has preserved its historic Santa Lucía hacienda, integrating it within the new airport. The various parties involved plan to create a museum within the hacienda that will allow visitors to learn about the Santa Lucía region and its amazing mammoth mammoth graveyard.

Here's a fun experiment to try. Go to your pantry and see if you have a box of spaghetti. If you do, take out a noodle. Grab both ends of it and bend it until it breaks in half. How many pieces did it break into? If you got two large pieces and at least one small piece you're not alone.

  • One on hand, the most common health condition among Olympic athletes is asthma. On the other, asthmatic athletes regularly outperform their non-asthmatic counterparts.
  • A new study assesses the performance-enhancement effects of asthma medication for non-asthmatics.
  • The analysis looks at the effects of both allowed and banned asthma medications.

Surprising Science
  • A Japanese scientist shows that some beetles can wiggle out of frog's butts after being eaten whole.
  • The research suggests the beetle can get out in as little as 7 minutes.
  • Most of the beetles swallowed in the experiment survived with no complications after being excreted.
