Ancient 12,000-Year-Old Mine Discovered in Underwater Caves on Mexican Coast

The underwater caves together Mexico’s Yucatán Peninsula contain in them a sprawling labyrinth of archaeological relics most likely as opposed to anywhere else on Earth.

Preserved in a large network of flooded caverns, these inundated cenotes hold a treasure trove of Maya strategies – but as a new discovery exhibits, you can also obtain ancient artefacts relationship again to much a lot more distant episodes of prehistory.

 

In a new analyze, scientists report the discovering of what could be the oldest acknowledged mine in the Americas (along with other promises to the title), uncovering the stays of a subterranean ochre mine relationship again to 12,000 a long time in the past.

“The underwater caves are like a time capsule,” says expert diver and micropalaeontologist Ed Reinhardt from McMaster University in Canada.

“There is apparent proof of ochre mining which would have taken place 1000’s of a long time in the past.”

In dives through 2017, Reinhardt and fellow scientists explored caves together the eastern shoreline of Quintana Roo. Caves in this area have prolonged been acknowledged to contain the skeletal stays of ancient peoples who inhabited the caverns 1000’s of a long time in the past, again when lower sea levels intended the caves were dry and available.

As to why ancient individuals would enter these deep and dangerous labyrinthine passages has remained unclear, but now we seem to have an clarification.

“The cave’s landscape has been noticeably altered, which prospects us to think that prehistoric people extracted tonnes of ochre from it, probably getting to mild hearth pits to illuminate the area,” says diver and archaeologist Fred Devos from the Analysis Centre of the Quintana Roo Aquifer Procedure (CINDAQ) in Mexico.

Inside the caves, the workforce identified a assortment of proof of prehistoric mining actions, together with digging instruments, ochre extraction beds, navigational markers, and ancient fireplaces.

The scientists counsel mining proof in a few submerged cave techniques spans about two,000 a long time of procedure – from 12,000 to 10,000 a long time in the past.

 

The sites, identified as La Mina, Camilo Mina, and Monkey Dust, may well be the oldest acknowledged examples of ochre mining in the Americas, but the workforce thinks cave exploration and ochre mining in the area may well day again even further more, based mostly on other skeletal proof dated to 12,800 a long time in the past.

For some explanation, the miners in this web page stopped their ochre extraction about 10,000 a long time in the past. As to why, the scientists are not sure, as the cave would nonetheless have been available at that point. It truly is achievable, they say, that the miners moved on to other deposits in other caves – and with two,000 kilometres of acknowledged cave techniques to take a look at in the area, we could obtain a lot more proof of this ancient mining in the long term.

What is sure is that it need to have taken unimaginable bravery to delve for hundreds of metres into these jagged caves, with only a lit torch to glow a route in the buried darkness.

That they ventured into the darkish like this in this kind of ailments tells us a little something about how vital the ochre pigment need to have been in ancient Palaeoindian rituals and customs, that they were eager to risk their life for their prize.

“Consider a flickering mild, in the middle of deep darkness,” says workforce member James Chatters from Utilized Paleoscience in Washington Point out, “that at when illuminates the red-stained palms of the miners as they strike the ground with hammers built out of stalagmites, whilst it lights the way for these who carry the ochre through the tunnels right until they achieve daylight and the forest floor.”

The results are noted in Science Advances.
