Ice Age Artists Used Charcoal Over 10,000 Years to Create Europe's Oldest Cave Paintings

Tiny bits of charcoal found in a cave in France are providing new clues into how our prehistoric ancestors lived some 35,000 years ago.

The samples were taken from the Chauvet Pont d'Arc Cave in southern France, whose wall paintings are the oldest in Europe and among the oldest in the world. Few people have ever been inside the cave, which was discovered only in 1994 and remains one of the greatest archaeological discoveries of all time—but some might recognize it from Werner Herzog's award-winning documentary Cave of Forgotten Dreams.

The results of the charcoal analysis, published today in the April issue of the journal Antiquity, enabled researchers to paint a picture of how humans created art in the Ice Age, as well as the bitter climactic conditions of that time.

Researchers collected 171 samples of charcoal from hearths and torch marks in the cave. Other bits of charcoal were found directly beneath the animal paintings, which have been preserved in incredible detail after being sealed off by a rockfall thousands of years ago.

The analysis revealed that all but one of the charcoal samples came from burnt pine trees; the remaining one came from buckthorn. That doesn't sound all that impressive until you consider that some of these drawings were created nearly 10,000 years apart, during two different Ice Age periods. Put differently, for millennia, humans chose to use the same material for the sole purpose of creating art.

Researchers concluded that while other types of wood could have been used, the artists who created these cave paintings continued to choose pine, likely due to the availability of fallen branches as well as its combustion properties. But more remarkably, researchers believe these early artists selected it because it was the perfect medium for their art, ideal "for the smudging and blending techniques used in cave paintings," according to the study.

Over the years, the paintings have been praised for their artistic merit and use of motion. As Herzog commented in Cave of Forgotten Dreams, one artist's rendering of a bison with eight legs suggested movement—"almost a form of proto-cinema."

These findings also reveal what the climate was like during that time, and it was anything but balmy. The researchers write:

"Pine is a pioneer taxon [group] with an affinity for mountainous environments and survived in refuges during the coldest periods of the last ice age. As such, it attests, first and foremost, to the harsh climatic conditions that prevailed during the various occupations of the cave."

To preserve the cave paintings, only researchers are allowed inside the Chauvet Cave. However, a replica of the cave was built in France's Ardèche region and remains open to tourists.

Fossilized Fat Shows 550-Million-Year-Old Sea Creature May Have Been the World's First Animal

A bizarre sea creature whose fossils look like a cross between a leaf and a fingerprint may be Earth's oldest known animal, dating back 558 million years.

As New Scientist reports, researchers from the Australian National University (ANU) made a fortunate find in a remote region of Russia: a Dickinsonia fossil with fat molecules still attached. These odd, oval-shaped creatures were soft-bodied, had rib structures running down their sides, and grew about 4.5 feet long. They were as “strange as life on another planet,” researchers wrote in the abstract of a new paper published in the journal Science.

Although Dickinsonia fossils were first discovered in South Australia in 1946, researchers lacked the organic matter needed to classify this creature. "Scientists have been fighting for more than 75 years over what Dickinsonia and other bizarre fossils of the Edicaran biota were: giant single-celled amoeba, lichen, failed experiments of evolution, or the earliest animals on Earth,” senior author Jochen Brocks, an associate professor at ANU, said in a statement.

With the discovery of cholesterol molecules—which are found in almost all animals, but not in other organisms like bacteria and amoebas—scientists can say that Dickinsonia were animals. The creatures swam the seas during the Ediacaran Period, 635 million to 542 million years ago. More complex organisms like mollusks, worms, and sponges didn’t emerge until 20 million years later.

The fossil with fat molecules was found on cliffs near the White Sea in an area of northwest Russia that was so remote that researchers had to take a helicopter to get there. Collecting the samples was a death-defying feat, too.

“I had to hang over the edge of a cliff on ropes and dig out huge blocks of sandstone, throw them down, wash the sandstone, and repeat this process until I found the fossils I was after,” lead author Ilya Bobrovskiy of ANU said. Considering that this find could change our understanding of Earth’s earliest life forms, it seems the risk was worth it.

Endeavour, Captain Cook's Lost Ship, Might Have Been Found—Solving a Centuries-Old Mystery

The exact location of the final resting place of Captain James Cook’s HMS Endeavour, which was sunk off the coast of Rhode Island 200 years ago, is considered one of maritime history’s greatest mysteries. Now, after a 25-year effort to pinpoint its remains among 13 sunken vessels, The Age reports that the Endeavour might have finally been identified.

British explorer James Cook left England on the Endeavour in 1768 headed for the South Pacific. He and his crew became the first European expedition to map the entire coast of New Zealand, and later, the first to reach Australia’s east coast. Along the way, they collected hundreds of previously unknown plant species, became the first Europeans to record a kangaroo sighting, and gathered evidence that would help disprove the existence of the long-speculated southern continent, Terra Australis, that hypothetically extended all the way up to the equator.

After that three-year journey, Cook and his crew returned to England. Though Cook became a legend, the Endeavour didn’t receive the star treatment. The British Royal Navy used it to ferry supplies to and from the Falkland Islands for several years before selling it to a private buyer. The ship was renamed the Lord Sandwich, and was eventually put into service transporting German mercenaries to fight on Britain's side in the American Revolution.

That’s how the ship ended up in Rhode Island, where it was stationed as part of the Royal Navy’s fleet in Newport Harbor and used as a prison ship for captured American soldiers. When French reinforcements came to assist American revolutionaries in Rhode Island, the British decided to sink their ships rather than allow them to be captured, creating a blockade out of scuttled vessels to block the French from getting into the harbor. They sank 12 transport vessels and set another on fire. Over the ensuing years, locals and French forces took equipment from the wrecks, but it’s never been entirely clear what happened to the remains.

The Rhode Island Marine Archaeology Project began to try to map and identify those remains starting in the early 1990s, and eventually figured out that the Lord Sandwich was the same ship as the HMS Endeavour. As the ship played a vital role in Australian history, the Australian National Maritime Museum then got involved with the project.

The two organizations have announced that they have lowered the number of potential wrecks that could be the Endeavour from 14 to five—and perhaps down to just one—by inspecting the area and measuring the wrecks against historic information about Cook's vessel. The researchers think the final resting place of the ship is located off the coast of Goat Island in Narragansett Bay, but to be absolutely certain, they’ll have to excavate the remains of the ship and examine its timbers. The researchers hope to have that work done by the 250th anniversary of Cook’s arrival in Australia’s Botany Bay—and his claiming of Australia as British territory—in 2020.

And there may be a battle over the remains. While the ship is considered a vital artifact of Australian history, the state of Rhode Island claimed ownership of all of the sunken ships in 1999, and they are overseen by the Rhode Island Historical Preservation and Heritage Commission.
