Occupation of Indonesian Island Pushed Back 60,000 Years

NEW SOUTH WALES, AUSTRALIA—Stone artifacts on the Indonesian island of Sulawesi have been dated to more than 100,000 years ago by a research team led by Gerrit van den Bergh of the Center for Archaeological Science (CAS) at the University of Wollongong. The tools were found at a site called Talepu in the southwestern arm of Sulawesi. “It now seems that before modern humans entered the island, there might have been pre-modern hominins on Sulawesi at a much earlier stage,” he said in a press release. The deposits were dated with a new luminescence dating technique for feldspars called “multiple elevated temperature post-infrared stimulated luminescence,” or MET-pIRIR, that was developed by Bo Li and Richard Roberts, also of CAS. These dates were supported by the discovery of fossilized animal teeth found in a deeper deposit that were dated with a different technique. It had been thought that humans first arrived on Sulawesi between 40,000 and 60,000 years ago, before they traveled on to Australia between 50,000 and 60,000 years ago.

Domestication May Have Brought Harmful Changes to Dogs

LOS ANGELES, CALIFORNIA—Researchers from the University of California, Los Angeles, analyzed the complete genomes of 19 wolves, 25 wild dogs from ten different countries, and 46 domesticated dogs from 34 different breeds. They found that domestication, which occurred more than 15,000 years ago through artificial selection and inbreeding, may have led to harmful genetic changes in dogs. “Population bottlenecks tied to domestication, rather than recent inbreeding, likely led to an increased frequency of deleterious genetic variations in dogs,” Kirk Lohmueller said in a press release. Those ancient changes could lead to developmental disorders and other health risks for today’s dogs. To read more about archaeological evidence of dogs, go to "More Than Man's Best Friend."

DNA Technologies Will Be Used to Identify Vietnam War Dead

HANOI, VIETNAM—The government of Vietnam will upgrade three DNA testing centers, and a private company will assist with the identification of the remains of Vietnam War victims. “The technical challenges are considerable but tractable,” Wolfgang Höppner, chief executive of medical-diagnostics company Bioglobe, told Nature News. Those challenges include Vietnam’s climate and soil microbes that can contribute to the degradation of DNA, and the large numbers of remains to be identified. The International Commission on Missing Persons (ICMP), located in Sarajevo, will help train Vietnamese scientists to exhume remains from mass graves and recognize identifying characteristics in the skeletons. Reference DNA will also be collected from family members to be compared with DNA recovered from victims, many of whom died without children, and whose parents have probably passed away in the 40 years since the Vietnam War. “That is why it is particularly important to do the DNA analysis with a larger than normal set of markers,” Höppner explained. The program is expected to identify between 8,000 and 10,000 sets of remains a year. To read more about archaeology in the area, go to "Settling Southeast Asia."

Oldest Tea Discovered in China

BEIJING, CHINA—The world’s oldest known tea has been discovered to have been buried along with Jing Di, a Han Dynasty Chinese emperor who died in 141 B.C., according to The Independent. The find suggests that tea was a favored beverage among Chinese royalty at least 2,150 years ago. Researchers from the Chinese Academy of Sciences looked at crystals on the surface of leaves found in a wooden box buried with the emperor and used mass spectrometry to establish that they were indeed tea. Millet and rice as well as weapons, pottery figurines, ceramic animals, and several full-sized chariots were also buried with the emperor in his capital, Chang’an, which is known today as Xi’an. The site was excavated in the 1990s, but analysis of the organic finds is only being undertaken now.

Cambodia’s Other Great Capital

PHNOM PENH, CAMBODIA—After Angkor was sacked in 1431 by the Siamese, the city of Longvek became Cambodia’s capital for 200 years. That period is traditionally thought of as a “dark age,” but recent excavations at the site are dispelling that notion, reports the Phnom Penh Post. Archaeologists digging at the city’s palace have found porcelain from China and Japan, and have also discovered sturdy earthen fortifications and a bronze workshop. The findings suggest the city, which lies on the Mekong River with access to the sea, was likely an important trading center. “Archaeologists, historians, tourists and the general public—everyone tends to focus on Angkor’s golden age, and when you go to Angkor you can see the reason why,” says Flinders University archaeologist Martin Polkinghorne, a member of the international team. “But of course Cambodian history continued and was intimately tied to international trade.” For more on archaeology in the region, go to “Letter From Cambodia: Storied Landscape.”

Nubian Artifacts Discovered in Temple Remains

ROME, ITALY—Archaeologists have discovered a ritual altar, a sacred boat base, and a hieroglyphic inscription at Abu Erteila in Sudan, according to a report by the Italian news agency AGI. The discoveries were made during excavations in November and December 2015 by a team led by Eugenio Fantusati of Sapienza University of Rome and Eleonora Kormysheva of the Russian Academy of Sciences. The artifacts were found in the remains of a temple that was probably destroyed by fire and are thought to date to between the first century B.C. and the first century A.D., the “Golden Age” of Meroitic Nubian civilization. The cartouches of King Natakamani and Queen Amanitore, who ruled during this period, have been identified in the hieroglyphics. The base of the sacred boat would at times have been used to carry the representation of a Nubian deity on ritual processions. "The artifact is extremely important for a better understanding of the Meroitic world—which is still quite unknown—and its relations with the nearby Egyptian civilization," Fantusati told AGI. To read about another Nubian temple, go to “The Cult of Amun.”

Bronze Age Village Unearthed in England

CAMBRIDGE, ENGLAND—Archaeologists have unearthed the best-preserved Bronze Age village ever discovered in England, according to a University of Cambridge press release. Built on stilts above a river beginning around 1200 B.C., the village was destroyed in a fire some 3,000 years ago. The blaze caused the settlement's wooden dwellings to collapse into the river, where sediments preserved the remains of the houses and artifacts in situ. Thus far the team has discovered ceramic vessels with food still inside, as well as an elaborate glass bead necklace, and even textiles made from plant fibers. “Usually at a Later Bronze Age period site you get pits, post-holes and maybe one or two really exciting metal finds,” says David Gibson, archaeological manager at Cambridge Archaeological Unit. “Convincing people that such places were once thriving settlements takes some imagination. But this time so much more has been preserved—we can actually see everyday life during the Bronze Age in the round.” To read about other prehistoric settlements in Britain, go to "Letter From Wales: Hillforts of the Iron Age."

Chinese Tomb Yields Prosthetic Leg

TURPAN, CHINA—Live Science reports that a 2,200-year-old prosthetic leg was discovered in a tomb located near the Silk Road in western China. Archaeologists described the leg in the journal Chinese Archaeology as “made of poplar wood; it has seven holes along the two sides with leather tapes for attaching it to the deformed leg. The lower part of the prosthetic leg is rendered into a cylindrical shape, wrapped with a scrapped ox horn and tipped with a horse hoof, which is meant to augment its adhesion and abrasion.” The man who wore the leg was between 50 and 65 years old at the time of death. Wear at the top of the device suggests that it had been used for a long time. Studies of man’s remains, published in Bridging Eurasia and Quaternary International, show that the bones of his left knee had fused together, perhaps due to inflammation in the joint caused by rheumatism or trauma. He had also been buried with ceramic cups and a jar and wooden artifacts. To read about an artificial toe from ancient Egypt, go to "Artifact."

1,500-Year-Old Amputation Wound Studied

VIENNA, AUSTRIA—Bioarchaeologist Michaela Binder of the Austrian Archaeological Institute examined the bones of a middle-aged man who died in the sixth century A.D. He had been buried in a high-ranking area close to a church with a short sword, a brooch, and a prosthetic device for his missing left foot and ankle. The wood of the device had deteriorated, but excavators recovered an iron ring that stabilized the device. The leg bones are also stained, perhaps indicating the man had been buried with leather pieces that attached the prosthesis to his leg. “Losing a foot—and especially when it’s not cut through the joint but through the bone—would have lacerated a lot of blood vessels and caused an extensive amount of bleeding,” Binder told Atlas Obscura. This injury, however, had healed, and left no sawing marks. There was a difference in the bone density of the man’s legs, suggesting that his left leg had been immobilized for some time. Binder adds that wear on his hips and knees suggest that he rode horses often, so perhaps his left foot had to be amputated after a riding accident.

New Labor-Saving Software Developed for Archaeologists

TRONDHEIM, NORWAY—New software has been developed by PRESIOUS, a project funded by the European Union, to help archaeologists work economically and efficiently. “We set out to address some of the challenges that archaeologists face in their everyday work,” project coordinator Theoharis Theoharis of the Norwegian University of Science and Technology said in a press release from the European Commission Community Research and Development Information Service. The first tool simulates how a stone object will erode under certain conditions. The second allows archaeologists to find possible fits for fragmented objects. The third uses symmetry to predict how artifacts with missing pieces might have looked. “But in order to develop these technologies, we had to address a key bottleneck—the expense and labor-intensive nature of digitization,” Theoharis said. “We found that it took a trained operator two and a half hours to scan just one fragment. So the fourth thing we did was speed up the digitization process with our industrial partner.” The tools will be made available without cost to archaeologists this month.

Medieval Fish Trap Discovered in Poland

TORUŃ, POLAND—Underwater archaeologist Krzysztof Radka of Nicolaus Copernicus University and his team were surveying the remains of one of two medieval bridges leading to the Ostrów Lednicki, an island in Lake Lednica, when they discovered a large, wicker fish trap. The oblong trap, found in the remains of the bridge to the east of the island, contained the remains of more than 4,000 fish. “Exploration required extreme caution because the wicker basket could disintegrate with every movement of water. [The] extraction operation was complicated because of the size, state of preservation, and delicacy of the object, but it seems that it was successful,” Radka told Science & Scholarship in Poland. “It is the only relic of the ninth-tenth century found during underwater research in Poland,” he explained. The bridges were destroyed in 1038 when Czech prince Bretislav invaded and captured the city of Poznań, on the western side of Lake Lednica, and sacked the city of Gniezno, on the eastern side.
