Rainy Season in the Andes Reveals the Oldest Known Copper Death Mask

A good downpour can be an archaeologist’s best friend. A recent rainy season in the northwest corner of Argentina revealed an ancient copper mask, green with rust, that had been hidden in the dirt for the last 3000 years. It's the oldest known copper artifact in the Andes—the longest continental mountain range on earth—and one of the oldest metalworks ever found in South America. Its discovery complicates the long-standing idea that metalworking began on the continent in Peru, thousands of miles north.

The mask looks a bit like a Jack-o’-lantern, with a little triangle for a nose and small openings for the eyes and mouth. Residents of the village of La Quebrada stumbled across the mask, as well as some bones, sticking out of the dirt in 2005. Shortly after, archaeologists came in to excavate the site, and they found that the mask wasn’t resting on just one burial, but was covering a collective grave with 14 bodies.

“We don’t know exactly what the actual meaning of the mask was in the context of this pre-Hispanic society,” archaeologist Leticia Inés Cortés, of Argentina’s National Council for Scientific and Technical Research, tells Mental Floss. Ancestor cults are very ancient and widespread in the region, Cortés says, so the mask could be a representation of the ancestor of the group and the rest of their community. Later DNA tests might reveal the relationships between the deceased.

The burial site was located near the 1900-year-old settlement of Bordo Marcial. However, radiocarbon dates showed that the tomb and mask are much older—dating back to 3000 years ago, before any villages even existed in the region.

During this time period, people in the area were just beginning to leave their hunter-gatherer way of life. But even before they truly settled down and started farming, they apparently figured out how to take advantage of the rich copper sources in the region that are still mined today.

Cortés, who described the mask in a new report in the journal Antiquity, tells Mental Floss that there’s been a tendency to treat Peru as the epicenter for technological innovation in the region. This mask, meanwhile, shows “that there is no one place for technological innovation, but many, including this region of the southern Andes.”

In other words, it’s not like a few geniuses in the central Andes figured out how to melt down metal to make beautiful objects and their invention spread from there.

Archaeologists might have previously assumed that cultures only started making fine metal objects when they had elite ruling classes and a capacity to create agricultural surpluses to free up time for skilled workers. But the mask from Argentina also builds on other evidence from the region demonstrating that displays of wealth might pre-date sedentary life.

“The discovery underscores the idea that social complexity—that is, a hierarchical social order—is not required for the emergence of early metal working,” says Mark Aldenderfer, an archaeologist at the University of California, Merced, who wasn’t involved in the study.

Aldenderfer previously discovered the oldest gold artifacts in the Americas, in the form of a necklace dating back to 4000 years in Peru near Lake Titicaca, when people in that region were just starting to settle into villages.

“The circulation of metal artifacts and their interment with the dead suggest that new forms of wealth accumulation and networking began to emerge during this transitional period,” Aldenderfer tells Mental Floss. "I suspect that the copper mask from Bordo Marcial reflects a similar social context."

The Fossil of a Human-Sized Penguin Has Been Unearthed in New Zealand

Penguins are known for looking cute and cuddly, but if the monster penguins of the Paleocene epoch were still around today, they might have developed a different reputation. As The Guardian reports, the fossil of a new species of one of these giant prehistoric penguins was recently discovered in New Zealand, and scientists say it would have gone head-to-head with many adult humans.

The bird, dubbed Crossvallia waiparensis, stood about 5 feet 3 inches tall and weighed about 175 pounds. For comparison, emperor penguins weigh up to 88 pounds and can reach 3 feet 8 inches in height. The prehistoric bird waddled the Earth some time between 66 and 56 million years ago—shortly after the mass extinction event that wiped out the dinosaurs and marine reptiles, which were probably its main predators.

An amateur paleontologist named Leigh Love discovered the creature's fossilized leg bones on New Zealand's South Island. From those fossils alone, a team of scientists from the Canterbury Museum in New Zealand and the Senckenberg natural history museum in Germany were able to estimate the penguin's height and weight and determine that it belonged to a previously undiscovered species. The large leg bones also indicate that the animal was more reliant on its feet for paddling through the water than the penguins of today.

Crossvallia waiparensis is massive by today's penguin standards, but it's not even the largest prehistoric penguin that we know of. When carnivorous reptiles began disappearing from the world's oceans, the waters opened up for new predators like penguins to flourish. Kumimanu biceae is estimated to have weighed about 223 pounds; Palaeeudyptes klekowskii may have weighed 253 pounds and stretched 6 feet 5 inches long.

Scientists Are Creating a 3D Model of an 18th-Century ‘Vampire Witch’ Who Was Tortured to Death

In 2014, archaeologists uncovered a skeleton in Kamień Pomorski, Poland, with a brick wedged in its mouth and stakes driven through its legs. They believed the man was put to death in the 18th century because townspeople thought he was a vampire.

Now, genetic and forensic analysis has shown that the vampire burial site didn't contain a man at all: It was a 5-foot-6-inch, blue-eyed, blonde woman who was at least 65 years old when she died. Newsweek reports that scientists at the Pomeranian Medical University in Szczecin, Poland are now making a 3D computer model of the woman’s skull, which they plan to use to recreate what her face looked like.

The Forensics Genetics Unit at the university will then build her face on a physical model from layers of plastic material and reveal it to the public within the next few months. Andrzej Ossowski, the head of the unit, told the website Science in Poland that he hopes a museum might display the rendering. “We want to show that with the help of modern methods, we are able to replace skeletons that are very common in museums with 3D models based on research,” he said.

He said that townspeople may have killed the woman because they thought she was a witch, and they gave her an “anti-vampiric” burial to prevent her from rising from her grave à la Nosferatu. The brick in her mouth was meant to weigh her down—in other burials a sickle might have been placed across the neck of the body, which would slit the revenant's throat should it try to rise.

We often think of Salem when it comes to witch trials, but they were common throughout Europe before the 19th century, and archaeologists have discovered “anti-vampiric” graves in Poland, Bulgaria, and Italy. Wondering if you might have qualified as a witch during the 17th-century period of Puritan paranoia? Find out here.
