Tsunamis and other natural disasters have taken a deadly toll on human populations for millennia, and now we may have the oldest example of that truth yet. An international team of anthropologists and environmental researchers recently analyzed a cracked skull that belonged to a person who likely died in a tsunami some 6000 years ago. They detail their find in a new study published in PLOS One.

The partial skull in question, known as the Aitape skull, was found in Papua New Guinea in 1929 during a geological survey by an Australian scientist named Paul Hossfield. It has since been dated to the mid-Holocene epoch, or around 6000 years ago.

For the current study, the scientists returned to the site of the 1929 discovery to sample and analyze the sediment there to find out more about what might have killed the person millennia ago. They had only Hossfield's basic field descriptions to go on, but University of Notre Dame anthropologist Mark Golitko, one of the study’s authors, says that based on those descriptions, they think they were able to sample within 100 yards or so of the skull's original location.

Based on the grain size, chemical signature, and marine microalgae found within the sediment samples, they were able to determine that around the time that the skull was buried, the area was inundated with water, probably from a tsunami. At that time, the site, located near the present-day town of Aitape, would have been just along the shoreline. Aitape was also the site of a devastating tsunami in 1998, and the Holocene sediments resembled the ones associated with that disaster.

It's possible that the skull was buried before the tsunami hit, and the grave was ripped apart by the waters and the rest of the bones scattered. However, during the powerful 1998 tsunami that killed more than 2100 people in Papua New Guinea, bodies buried in modern cemeteries were not uprooted even as the sediment above them washed away, making it more likely that the ancient skull belonged to someone killed in the disaster.

The new analysis has "made us realize that human populations in this area have been affected by these massive inundations for thousands of years," study co-author James Goff of the University of New South Wales said in a press statement. "Given the evidence we have in hand, we are more convinced than before that this person was either violently killed by a tsunami, or had their grave ripped open by one."

Field Museum anthropologist John Terrell, another co-author of the study, said, "If we are right about how this person had died thousands of years ago, we have dramatic proof that living by the sea isn't always a life of beautiful golden sunsets and great surfing conditions."

Researchers Accidentally Discover 128-Year-Old Shipwreck

Scientists conducting a routine survey of the waters along Australia's east coast got more than they bargained for when they accidentally discovered a 128-year-old shipwreck.

Their encounter with the sunken Carlisle, which sank in 1890, was captured on camera, and Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO) has released footage showing an aerial view of the wreckage, teeming with schools of fish.

The researchers were mapping the seafloor of Bass Strait, which separates mainland Australia from the island of Tasmania, to improve nautical charts for the major shipping route, according to Mashable. During a scan of the waters, the sunken ship showed up as a "blip," ABC reports.

"We just happened to go over this blip, and we noticed it, and thought, 'Oh jeez, that looks just a little too much like a shipwreck,' and so we did a little bit more investigating and looked at it digitally," CSIRO hydrographer Matt Boyd told ABC. "Then once we established that yes, it was a shipwreck, we put a drop camera down."

Volunteers from the Maritime Archaeological Association of Victoria then went to the site and confirmed that the ship was indeed the Carlisle. It most likely collided with rocks while sailing from Melbourne to Newcastle, where it was supposed to pick up coal on its way to South America. All 23 crew members survived, escaping on three life boats.

The researchers discovered two more shipwrecks during a weeklong expedition from Brisbane to Hobart, one of which was identified as the HMAS Pioneer, a ship built for the British Royal Navy in 1900 that was scuttled in 1931.

6 Priceless Treasures Lost in Shipwrecks

In the lore around treasures lost at sea, most of the excitement goes to pirate’s gold and the sunken luxuries of the Titanic. But in the centuries of human seafaring, many lesser-known priceless objects, from literary manuscripts to scientific research, have been claimed by the depths. Here are some tales of those losses, from a lifetime of work by a 19th-century woman who was an expert in cephalopods, to a rare book by Dickens that went down with the Lusitania.

1. LOUIS DE JAUCOURT'S ANATOMICAL LEXICON

Always, always, always back up your work. Of course, that's easier now than it was in the 18th century, when French scholar Louis de Jaucourt dispatched his six-volume Lexicon medicum universale to his Amsterdam publisher, a move intended to evade French censorship. The medical dictionary, on which he'd spent 20 years, was completely lost when the ship it was on sank off Holland's coast. Luckily, Jaucourt rebounded when Denis Diderot asked him to contribute to the Encyclopédie, now considered one of the greatest works of Enlightenment thought, for which he used his notes from the lost manuscript. Jaucourt became the publication's most prolific author, penning 40,000 articles—so many he was nicknamed l'esclave de l’Encyclopédie, or the "slave of the Encyclopedia."

2. THE FIELDWORK OF ALFRED RUSSEL WALLACE

In 1852, following four years of research in the Amazon, the British naturalist Alfred Russel Wallace was ready to return to England. He loaded his copious notes, animal and plant specimens, and drawings onto the brig Helen. Just 26 days into the voyage, the vessel caught fire. Wallace only had time to hastily fill a tin box with a few drawings of fish and palms and some scientific notes before joining the crew in the lifeboat. After 10 days marooned at sea, they were rescued by the brig Jordeson—but most of Wallace's work was gone forever. As he lamented in an October 19, 1852 letter, "The only things which I saved were my watch, my drawings of fishes, and a portion of my notes and journals. Most of my journals, notes on the habits of animals, and drawings of the transformations of insects, were lost.” While he continued as a leading naturalist—albeit one overshadowed in his evolution research by Charles Darwin—Wallace was never able to reconstruct those years of fieldwork.

3. THE CEPHALOPOD RESEARCH OF JEANNE VILLEPREUX-POWER

Before Jeanne Villepreux-Power’s 19th-century research, most scientists thought the Argonauta argo, or paper nautilus, scavenged its shell from other animals. But by inventing the modern aquarium, Villepreux-Power could study the species first-hand, and witness how it grows and repairs its own shell. The breakthrough was one of many discoveries made by the pioneer in cephalopod research, one of the few women to achieve prominence in Victorian science. She might be better known today if it weren't for the fact that when she and her husband decided to move from Sicily to London, the vessel on which they’d shipped their possessions—including the majority of her drawings, notes, and equipment—foundered off the coast of France in 1843. After the devastating loss, she never published again.

4. A COPY OF A CHRISTMAS CAROL OWNED BY CHARLES DICKENS

When Boston bookseller Charles Lauriat realized the RMS Lusitania was doomed that fateful day in 1915, he dashed to his cabin, using the light from a few matches to try to find the literary treasures he’d brought aboard. These included original drawings by Vanity Fair author William Makepeace Thackeray, as well as an edition of A Christmas Carol owned by Charles Dickens himself. The edition was irreplaceable, since it included Dickens’s notes related to his 1844 copyright suit against the illicit republishing of his story. In the book Dead Wake: The Last Crossing of the Lusitania, Erik Larson vividly describes Lauriat’s harrowing experience when the ocean liner was torpedoed by a German U-boat off the coast of Ireland: Lauriat grabbed the leather briefcase containing the Dickens, but left the Thackeray sketches behind. Rushing out to the deck, he saw a lifeboat packed with women and children that was being dragged down by the sinking ship. He jumped in with the briefcase, yet was unable to free the lifeboat, and in the escape into the water he lost the precious cargo. Out in the waves, he managed to evade entanglement with an antenna, swim to a collapsible lifeboat, and survive. One of the few items he managed to save were photographs of his baby, which he told his wife were his "mascot."

5. WRITINGS OF JOSÉ ASUNCIÓN SILVA

Many Colombians can recite the first lines from the influential Modernist poet José Asunción Silva's "Nocturne III"—"A night / A night full of hushings, of the curled wool of perfume / And incanting wing"—and it’s even printed in microtext on the 5000 Colombian peso bill. The poem, written in 1892, is believed to be a tribute to Silva’s half-sister. Silva suffered another blow in 1895, when many of his manuscripts, including a draft of a novel, were lost in a shipwreck. He left his diplomatic post in Venezuela, and dedicated all his time to reconstructing the drowned novel. But his melancholy continued: After visiting a doctor to ask the exact position of his heart, he shot himself in 1896. His rewritten novel—After-Dinner Conversation (De sobremesa) —wasn’t published until 1925.

6. THE ART OF GIOVANNI BATTISTA LUSIERI

Giovanni Battista Lusieri was a meticulous painter of the Italian landscape, particularly its classical ruins. In large panoramas and more compact watercolors, he depicted the Acropolis, views of Rome and Naples, and, his favorite, the eruption of Mount Vesuvius. Some of his most striking works captured the volcano at night, illuminating the darkness with its orange glow. Lord Byron called him "an Italian painter of the first eminence." Yet his name is now obscure. This is partly due to the years he stopped painting to help Lord Elgin remove and ship the Parthenon Marbles to London. But when Lusieri's artwork was being sent home from Greece after his death in 1821, a shipwreck destroyed nearly half of it (including a spectacular 25-foot-long panorama of Athens), helping to ensure his fall from fame.

BONUS: PEKING MAN

When paleontologists discovered the bones of "Peking man" in a dig near Beijing in the 1920s, they were the oldest hominid fossils ever found. However, scientists can now only study the bones—thought to be about half a million years old—from casts. The Peking Man fossils were last seen in December 1941, but vanished during the Japanese occupation of China while they were being sent to the United States for safekeeping. There are many conjectures on their fate, from being secretly stored away in Japan, to being under a parking lot in China. Yet one enduring theory is that they were lost at sea on the Japanese freighter Awa Maru: In 1945, the ship was torpedoed in the Taiwan Strait by the USS Queenfish despite being guaranteed safe passage by the United States, leading to the loss of more than 2000 lives—and, it's said, the priceless Peking fossils [PDF].
