Cache of 8,000-Year-Old Animal Bones Found in Mexico

October 21, 2016

NUEVO LEÓN, MEXICO—Prensa Latina reports that archaeologist Araceli Rivera of Mexico’s National Institute of Anthropology and History (INAH) has found animal remains that may have been used in rituals some 8,000 years ago. The remains include the teeth, long bones, skulls, ribs, and vertebrae of mammoths, camels, horses, llamas, and prehistoric bison. The bones had been placed in a rock shelter and covered with a rectangular stone that researchers have dubbed La Boveda, or The Vault. The researchers think The Vault may have been illuminated during the winter solstice, at a time when food may have been scarce. For more, go to “Under Mexico City.”

Possible Evidence of Roman Attack Found in Jerusalem

October 21, 2016

JERUSALEM, ISRAEL—The Guardian reports that Rina Avner and Kfir Arbib of the Israel Antiquities Authority have found evidence of a 2,000-year-old watchtower and a wall that protected a “new” area of Jerusalem that had developed outside of the city’s two existing defensive walls. The Jewish historian Josephus described Titus’s breach of such a third wall in A.D. 70, when Roman legions invaded, sacked the city, and destroyed the Second Temple. Large stones that the Romans may have fired from catapults at the sentries in the tower have also been uncovered. It is thought that Roman forces used battering rams on the wall while the catapults provided cover. To read about another discovery in Jerusalem, go to “Rubaiyat Pot.”

New Thoughts on Ancient Stone Flakes

October 20, 2016

OXFORD, ENGLAND—Live Science reports that capuchin monkeys living in Brazil’s Serra da Capivara National Park have been observed banging rocks against one another, an action that produces a cobble with a single flat side that is called a “unifacial chopper” by archaeologists. Unifacial choppers bear telltale scallop-shell-shaped breakages called conchoidal fractures. It had been thought that such modified stones were only made by hominins. According to observations made during the study, the monkeys sometimes lick the rocks, perhaps to ingest lichens or minerals, but they don’t use them as tools. Instead, they use other rocks to break open nuts. Researcher Tomos Proffitt of the University of Oxford says the study shows that modern primates can produce some types of artifacts that have until now been attributed to hominins alone, and will require scientists to rethink how they determine whether a stone tool was made by a human ancestor or human relative.

Engraved Stone May Have Been a Neolithic Map

October 20, 2016

BORNHOLM, DENMARK—The Copenhagen Post reports that an engraved stone fragment discovered at the Neolithic site of Vasagård on the island of Bornhom could be a map. Archaeologist Flemming Kaul of the National Museum of Denmark said that other stones inscribed with lines and rectangles have been found at the site, and it had been thought that the markings depicted the sun and its rays. This partial stone is now thought to show the details of an area of the island as it appeared between 2700 and 2900 B.C. Some of the markings may even represent ears of corn or plants with leaves. “These are not accidental scratches,” he said. “We see the stones as types of maps showing different kinds of fields.” To read about another discovery in Denmark, go to “Bronze Age Bride.”

Skara Brae Residents May Have Snacked on Rodents

October 20, 2016

EDINBURGH, SCOTLAND—The Los Angeles Times reports that rodents may have been a source of food at Skara Brae, the Neolithic settlement on the Orkney Islands. Biologist Jeremy Herman of the National Museums of Scotland and his team evaluated some 60,000 small mammal bones collected from four trenches at the site in the 1970s. The scientists found that the number of wood mouse bones was equal in all four trenches, but one of the trenches had a greater number of bones from the Orkney vole than the others. And, since voles, which are slightly bigger than mice, are thought to usually stay away from people, the animals may have been brought to the area. Some of the bones also bear burn marks. “The way they are burnt it’s pretty clear that they were pretty much whole when they were stuck on the embers of a fire,” Herman said. “I haven’t tried it myself, but I imagine they got pretty crisp on the outside.” He thinks the small rodents may have served as a snack, a food for lean times, or something that children caught and roasted.

Drones Used to Map the Plain of Jars in Laos

October 20, 2016

CANBERRA, AUSTRALIA—The Canberra Times reports that CAVE2 technology, based at Monash University, has been used to map three excavation sites on the Plain of Jars, an archaeological site in a remote area of Laos with carved stone jars that stand nearly ten feet tall. Drones are being used to collect the footage for the project. The team of researchers will then create a 3-D replica of the excavations and the entire Plain of Jars landscape. “It hasn’t really been researched on this scale since the 1930s and what our project hopes to show is exactly what the jars were for, when they were produced, and who made them,” said Dougald O’Reilly of Australian National University. Information collected with ground-penetrating radar was fed into the CAVE2 system to create the underground view of the excavation area. O’Reilly also plans to evaluate the site with lidar technology, which can detect archaeological remains beneath heavy foliage, and add that information to the virtual 3-D reconstruction.

German WWI Submarine Found Off the Coast of Scotland

October 20, 2016

STRANRAER, SCOTLAND—BBC News reports that a German U–boat dating to the First World War was discovered off the coast of Scotland by a team laying subsea power cables. The vessel is thought to be UB-85, one of two UBIII-Class submarines known to have been lost in the Irish Sea. After being picked up by HMS Coreopsis, the captain and crew of UB-85 claimed to have done battle with a sea monster that damaged the vessel so badly that it could no longer submerge. But nautical archaeologist Innes McCartney says that when the British ship approached the submarine on the surface at night, the crew of the German vessel may have tried to submerge quickly, started taking on water, and had to resurface and surrender. Identifying the newly discovered wreck with confidence may be impossible, however, as the UBIII-Class submarines were all very similar. “Unless a diver can find a shipyard stamp, we cannot say definitively, but yes, we’re certainly closer to solving the so-called mystery of UB-85 and the reason behind its sinking—whether common mechanical failure or something that is less easily explained,” McCartney said.

Unusual Graves Discovered in Poland

October 19, 2016

SASINY, POLAND—Science & Scholarship in Poland reports that ten monumental tombs discovered in northeastern Poland resemble Neolithic burials, even though they date to the eleventh to thirteenth centuries and are thought to contain the remains of Christians. “All members of the local community were buried in the study graveyard—both poorer and richer, including the elite,” said archaeologist Michal Dzik of the University of Rzeszów. “Funeral rites were common to all. Each of the deceased was placed in a large burial structure, the edges of which [were] marked by big boulders.” After the body had been placed inside, the rectangular-shaped graves were filled with layers of stones. The burials, however, were not covered with mounds of dirt, as had been the case before the arrival of Christian customs. Dzik also found glass beads, silver temple rings, crescent moon and cross pendants, evidence of vessels placed near the deceased, and bonfires that had been lit in the tombs. He thinks there may have been other, similar cemeteries in the area that retained elements of pre-Christian burials, but their distinctive boulders were reused in later periods as building materials.

Mastodon Found in Michigan May Have Been Butchered

October 19, 2016

MAYVILLE, MICHIGAN—The Detroit News reports that a team from the University of Michigan, assisted by teachers from Tuscola County, has recovered about 60 to 70 percent of the remains of a 30-year-old male mastodon thought to have been processed by human hunters or scavengers between 11,000 and 13,000 years ago. The long limb bones, both shoulder blades, the pelvis, the skull, many vertebrae, and most of the ribs were found. Some sections of the carcass had been separated from other sections. The tusks, lower jaw, and most of the foot bones were missing from the site. Daniel Fisher, director of the University of Michigan Museum of Paleontology, estimates the likelihood that humans were involved in processing the carcass at 80 percent. He thinks that humans may have stored the sections of mastodon meat in cold, low-oxygen pond sediments to help preserve them. The team will now radiocarbon date the remains and examine them for signs of butchery. The animal’s wisdom teeth will also be analyzed to try to determine in which season it died.

Medieval Artifacts Unearthed in Southwest England

October 19, 2016

DEVON, ENGLAND—The Herald Express reports that fifteenth-century artifacts have been found in the town of Newtown Abbot by a team from Cotswold Archaeology. The excavation site along Wolborough Street includes the rear areas of long, narrow plots of land that would have been rented from the local lord during the medieval period. The red mud of the region preserved a child’s shoe, an iron spur, and three wooden barrel bases. The excavators have also uncovered a granite millstone in the bottom of one of two wells at the site. The front areas of these plots of land were disturbed by the construction of two large townhouses in the late seventeenth and early eighteenth centuries. The archaeologists think that they may find evidence of a sixth- or seventh-century settlement under the medieval remains. To read about another find in the area, go to “Seaton Down Hoard.”

Genetic Study of Bison Offers Clue to Cave Painting Conundrum

October 19, 2016

ADELAIDE, AUSTRALIA—The Christian Science Monitor reports that the ancestor of the modern European bison, the wisent, may have descended from a cross some 120,000 years ago between the extinct ancestor of modern cattle and the Ice Age steppe bison. Alan Cooper of the Australian Center for Ancient DNA at the University of Adelaide led a team that was examining bison fossils to study climate change. Surprisingly, DNA extracted from the bones suggested the animal was actually a hybrid between an aurochs and a steppe bison. “We contacted French cave art researchers who happily told us that you can see two quite different forms of bison in the cave art,” Cooper said. “They’d been put down to regional artistic differences or cultural differences.” Cooper and his team radiocarbon dated the bones and found that the unknown hybrid bison and the steppe bison each had an ecological niche, which was recorded in cave art. The hybrid bison seems to have thrived in colder conditions, while the steppe bison dominated during warmer periods. For more, go to “Bison Bone Mystery.”

German Castle Yields Possible 17th-Century Murder Victim

October 18, 2016

LUND, SWITZERLAND—Motherboard reports that human bones discovered at Leine Castle in Niedersachsen, Germany, are thought to belong to Philip Christoph Königsmarck, a Swedish count who disappeared in 1694 after visiting his mistress, Princess Sophia Dorothea of Celle. She was unhappily married to Georg Ludwig, prince elector of Hanover, who later became King George I of England. More than 300 love letters, some of which were written in cipher, between Königsmarck and the princess have been preserved at Lund University. The two had planned to run away together, but their affair was revealed and Königsmarck disappeared. Many suspected that Ludwig had the count murdered, but Königsmarck’s body was never found. (Ludwig exiled Sophia Dorothea to Castle Ahlden, where she died, 32 years later.) A team of researchers from the University of Göttingen will try to match DNA samples from the bones with samples from Königsmarck’s living relatives.

Cancer-Causing HPV May Have Come From Interbreeding

October 18, 2016

BARCELONA, SPAIN—According to a report in Laboratory Equipment, a new study of a cancer-causing human papillomavirus (HPV16) suggests that its variants evolved separately with archaic and modern humans. HPV does not leave any trace of infection in the bones, so it was not possible to extract ancient forms of the virus from human remains. Instead, scientists Ville Pimenoff of the Catalan Institute of Oncology and Ignacio Bravo of the French National Center for Scientific Research sequenced the genome of the HPV16 virus and its five main lineage subtypes, then reconstructed its evolution over thousands of generations with computer algorithms. Their results suggest that variant A evolved with archaic humans, while three other variants evolved with modern humans. Migrating modern humans then may have been infected with viral variant A through sexual contact with Neanderthals and Denisovans. The study suggests that variant A was able to thrive in the modern human population because the modern human immune system had not evolved the mechanisms necessary to keep it in check. The researchers say that this could explain why the HPV16A variant is rarely found in sub-Saharan Africa, while it is the most common variant in the rest of the world.

Shipment of 16th-Century Chinese Porcelain Unearthed in Mexico

October 18, 2016

MEXICO CITY, MEXICO—Xinhua reports that thousands of fragments of a 400-year-old of shipment of Chinese porcelain have been discovered by Mexican archaeologists in the Old Quarter of Acapulco. The white and blue rice bowls, cups, plates, and platters are decorated with images from nature, including birds, beetles, swans, ducks, and deer, and date to the reign of the Ming Dynasty emperor Wanli, who ruled from 1572 to 1620. Archaeologist Roberto Junco of Mexico’s National Institute of Anthropology and History (INAH) said that the pottery was made in southern China, in the city of Zhangzhou, and in the city of Jingdezhen, known as the “Porcelain Capital.” The luxury goods were probably carried to Mexico by Spanish ships that traveled between the port of Acapulco and Manilla in the Philippines. The cargo may have been destroyed by pirates. For more, go to “Under Mexico City.”

Previously Unknown Compounds Identified in Frankincense

October 18, 2016

NICE, FRANCE—Live Science reports that researchers led by Nicolas Baldovini of the Institute de Chimie de Nice have identified two molecules responsible for the unique scent of frankincense, often recognized today as “old church” smell. Frankincense comes from the resin of gum trees from the Boswellia genus, and was a key element in perfumes from Mesopotamia and Egypt dating back to the fourth millennium B.C. The chemical structures of the two new compounds, named olibanic acids, are mirror images of each other, and are found in extremely low levels in the essential oil of frankincense. The team was also able to synthesize synthetic versions of the molecules. “We patented the use of these compounds for fragrance formulation,” Baldovini said. For more on the relationship between archaeology and chemistry, go to Mr. Jefferson’s Laboratory.

Looking Beneath the Surface of Greek Pottery

October 15, 2016

STANFORD, CALIFORNIA—The Daily Mail reports that a team of researchers from the Cantor Arts Center’s Art + Science Learning Lab and the Stanford Synchrotron Radiation Lightsource (SSRL) at the SLAC National Accelerator Laboratory examined a 2,500-year-old Athenian oil flask with a technique called synchrotron X-ray fluorescence. The results of the test produced a chemical map of the paint on the vase, which suggests that an extra step was required to apply a calcium-based additive for the color white. “Under what they thought was a single coat, they found other instances of painting that the naked eye could not see,” said Jody Maxmin of Stanford University. In addition, it had been previously thought that zinc was added to produce black figures during the heating process on Greek vases, but the chemical map failed to show any zinc in the black regions of the pot.

“Spectacular” Rock Art Discovered in Spain

October 15, 2016

LEKEITIO, SPAIN—BBC News reports that some 50 Paleolithic etchings thought to be between 12,000 and 14,500 years old have been found in a difficult-to-access area of Armintxe Cave, located in northern Spain. The images include depictions of bison, goats, and horses, one of which measures nearly five feet long. Researchers also identified two lion images, which have not been seen before in the Basque country, and semi-circles and lines similar to those found in the French Pyrenees. Taken together, the lions, the semi-circles and lines, and the etching technique suggest that these artists in Biscay province might have been linked to those in the French Pyrenees. “It is a wonder, a treasure of humanity,” commented Biscay province official Unai Rementeria.

Badger Unearthed 4,200-Year-Old Bones in Ireland

October 14, 2016

COUNTY CAVAN, IRELAND—The Irish Times reports that a badger unearthed ancient human remains at a burial site in Cavan Burren Park, known for its prehistoric monuments, megalithic tombs, rock art, and dwelling sites. A group of historians and archaeologists found the small pieces of cremated human bone and charcoal near a collapsed tomb. “Our badger just threw out the bones,” said historian Séamus Ó hUtlacháin. “They were no bigger than my nail, just scraps of bone. It is the oldest discovery in this region, a wonderful discovery.” Part of a femur from the site has been carbon dated by scientists at Queen’s University to between 2438 and 2200 B.C.

Ancient Footprints Studied in Tanzania

October 14, 2016

ENGARE SERO, TANZANIA—The Washington Post reports that Cynthia Liutkus-Pierce of Appalachian State University led a team of researchers in the study of some 400 ancient Homo sapiens footprints that were discovered in northern Tanzania, near the Ol Doinyo Lengai volcano, about 10 years ago. The footprints are thought to have been made by men, women, and children in flood deposits that dried and then were covered with another layer of mud. Minerals in the footprint layers were dated to between 19,000 and 10,000 years ago with the argon-argon dating technique. Once the excavation team exposed the footprints, each one was photographed, 3-D scanned, and mapped. The researchers have found evidence of at least 24 individuals who crossed the mud in two directions. Some of the travelers were walking, and some may have been jogging. A subgroup of the researchers continues to investigate the size and composition of the group that left the footprints. “For people who work in prehistory, it’s incredibly rare to get that kind of snapshot in time,” said paleoanthropologist Briana Pobiner of the National Museum of Natural History. For more on ancient footprints, go to “Proof in the Prints.”

Roman Settlement Uncovered in Rugby, England

October 14, 2016

RUGBY, ENGLAND—The Rugby Observer reports that an archaeological investigation ahead of the construction of a housing development in England’s West Midlands unearthed a 2,000-year-old Roman settlement, a well, and kilns where pottery was produced. They also found a waterlogged pit alignment dating to the late Bronze Age, between 1000 and 500 B.C. Samples from the pit will be tested for information about the local landscape, forest clearance, and agriculture. To read about other discoveries in this area, go to “They're Just Like Us.”
