Hundreds of Mammoth Bones Have Been Found Under The Site of a Future Mexican Airport

Two hundred historic mammoth skeletons have been identified beneath an airport construction web-site north of Mexico Town – the biggest collection of mammoth bones ever located.

Archaeologists at Mexico’s Nationwide Institute of Anthropology and History initial realised the area might disguise mammoth remains soon after they located two human-dug mammoth traps in November as part of routine excavations to apparent land for the airport web-site.


The traps, in an area meant for use as a garbage dump in the city of Tultepec, contained the bones of at the very least 14 Columbian mammoths.

The construction web-site of the Felipe Ãngeles International Airport is just twelve miles (19.3 km) from all those traps. There, excavation teams identified in May that the dried-up mattress of Lake Xaltocan held at the very least sixty mammoth skeletons. The total uncovered has considering that attained 200 – with extra bones however ready underground.

“There are much too several. There are hundreds,” Pedro Sánchez Nava, an archaeologist at the institute, told The Connected Push.

Now an observer accompanies every single bulldozer at the construction web-site, just in circumstance one particular digs up new mammoth bones, in accordance to The AP.

The former biggest mammoth web-site identified, in Sizzling Springs, South Dakota, held the remains of about sixty mammoths.

The discovery could shed mild on why mammoths went extinct

Columbian mammoths arrived in North The united states about one million yrs ago. They stood up to 14 feet (four.3 m) tall and lived about as extended as individuals: 70 to 80 yrs.

Unlike their woolly counterparts in Europe, these mammoths possible did not have a lot hair – an adaptation to North America’s warmer local climate. Their variety prolonged from Canada to Nicaragua and Honduras.


Columbian mammoths went extinct among 13,000 and 10,000 yrs ago, and several paleontologists consider prehistoric human hunters played a significant function.

Which is one particular of the factors of this web-site that researchers hope to investigate. People obviously killed some of the mammoths in the pits identified in Tultepec, but it really is not still apparent regardless of whether they played a function in driving the 200-additionally mammoths into the lake mattress.

Researchers consider the mammoths might have gotten stuck in mud alongside the lake’s shore, then died of starvation or drowning.

That could have took place naturally, considering that the lake’s grasses and reeds would have captivated the mammoths to feed. But the enormous quantity of skeletons could also show that individuals cleverly utilised the lakeshore’s stickiness to their edge, in accordance to Sánchez Nava.

“It really is feasible they may perhaps have chased them into the mud,” he told The AP in May possibly.

If that’s true, it would signify individuals were able of killing bigger figures of mammoths than earlier assumed. It could also be evidence that historic folks ate mammoth meat as a staple part of their meal plans – not sporadically, as researchers had assumed right before.


However, the bones located at the airport web-site have not still shown any marks that would show individuals butchered the animals.

If individuals were involved in the creatures’ deaths, having said that, that would incorporate assistance to the concept that folks contributed to or triggered Columbian mammoths’ extinction in the Americas. The other prevailing idea indicates the beasts perished simply because of habitat decline triggered by warming climate as the ice age ended.

Or it could be a blend of both things, in accordance to paleontologist Joaquin Arroyo-Cabrales, who operates at the anthropology institute.

“I consider in the close the determination will be that there was a synergy influence among local climate transform and human presence,” he told The AP.

People may perhaps have created tools out of mammoth bones

Even if individuals did not destroy the mammoths in the lake mattress specifically, evidence is rising that historic civilizations all over the area utilised the animals’ bones for tools.

Archaeologists have so much identified dozens of tools all over the web-site that were at the very least partly created from mammoth bones, like knives with mammoth-bone shafts.


But they’re not confident the bones in the tools came from the mammoths located in the lake mattress. They could have appear from other mammoths, like the kinds in the nearby Tultepec pits.

Even further laboratory tests could help paleontologists identify what romance, if any, individuals had with the mammoth bones in the lake mattress – regardless of whether they killed them, ate them, utilised them for tools, or all three.
