Oregon’s “Tantalizing” Evidence of Human Occupation

March 6, 2015

PORTLAND, OREGON—Near the Rimrock Draw Rockshelter, beneath a layer of ash from an eruption of Mt. St. Helens some 15,800 years ago, archaeologists have found a tool made of orange agate thought to have been used for scraping animal hides, butchering, and possibly even carving wood. “The discovery of this tool below a layer of undisturbed ash that dates to 15,800 years old means that this tool is likely more than 15,800 years old, which would suggest the oldest human occupation west of the Rockies,” said Scott Thomas, Bureau of Land Management Burns District archaeologist. A blood residue analysis of the tool revealed animal proteins consistent with the ancestor of the modern buffalo. The director of the excavation, Patrick O’Grady of the University of Oregon, adds that the excavation will be expanded to look for more artifacts underneath the ash layer. “We want to assemble indisputable evidence because these claims will be scrutinized by researchers. That said, the early discoveries are tantalizing,” commented Stan McDonald, BLM Oregon/Washington lead archaeologist.

“Significant Variation” Found in Skulls From Pre-Contact Peru

March 5, 2015

RALEIGH, NORTH CAROLINA—It had long been thought that there was very little skeletal variation among the pre-Columbian peoples in the New World, based upon a sample of individuals from the Yauyos people of the central Peruvian highlands. But anthropologists from North Carolina State University, the University of Oregon, and Tulane University evaluated the facial features of 507 skulls from seven pre-Columbian peoples from Peru, and found significant differences between all of them. “And our work shows that the Yauyos had facial features that were very different even from other peoples in the same region. This raises questions about any hypothesis that rests in part on the use of the Yauyos sample as being representative of all South America,” Ann Ross of North Carolina State University told Eureka Alert. The scientists found that the farther apart the groups lived from each other, the less they looked alike. “Next we want to compare variation across Latin America, to see if we can identify patterns that suggest biological relationships, which could be indicative of migration patterns,” Ross said. To read about more skeletons found in the region, see "Unusual Sacrifices Unearthed in Peru."

Neolithic Town Unearthed at Greece’s Alepotrypa Cave

March 5, 2015

CHIGAGO, ILLINOIS—The Diros Project has uncovered the remains of Ksagounaki, an ancient town and burial complex, located outside the entrance to Alepotrypa Cave in southern Greece. The large underground cave may have been seen as the entrance to the mythic Greek underworld, and the ancient town is thought to have been an important ritual and settlement complex during the Neolithic period and the Bronze Age. (The recently discovered grave of a man and woman who had been buried together in an embracing position some 6,000 years ago was found at Diros.) However, William Parkinson of The Field Museum said that some 2,000 years after the settlement at Ksagounaki was abandoned, the Mycenaeans built a structure there and filled it with the bones of dozens of individuals, Late Bronze Age pottery, stone beads, ivory, and a bronze Mycenaean dagger. Perhaps the Neolithic buildings had drawn the attention of the Mycenaeans to this natural wonder. For more about Alepotrypa Cave, see "Portals to the Underworld."

Celtic Tomb Sheds Light on Iron Age Trade

March 5, 2015

LAVAU, FRANCE—A tomb dating to the fifth century B.C. has been discovered in eastern France. “It is probably a local Celtic prince,” Dominique Garcia, president of France’s National Archaeological Research Institute (INRAP), told The Connexion. Within the burial mound, his team has found a large cauldron decorated with the head of the horned Greek river god Acheleos that may have been made by Etruscan or Greek craftsmen. A Greek wine pitcher trimmed with gold depicts Dionysos, the god of wine, with a woman. Garcia says that the artifacts “are evidence of the exchanges that happened between the Mediterranean and the Celts.” At the time, the Mediterranean city of Marseille, in southern France, was a Greek settlement. The burial chamber, which also holds the remains of the deceased and his chariot, is one of the largest recorded for the period. To read about Iron Age Celtic rituals, see "Celtic Sacrifice."

Dates Obtained for Earliest-Known Homo Fossil

March 4, 2015

STATE COLLEGE, PENNSYLVANIA—The earliest-known fossil of a human ancestor, discovered in the Afar region of Ethiopia, has been dated to between 2.8 and 2.75 million years ago by an international team of scientists. Known as LD 350-1, the team dated the layers of volcanic ash above and below the Ledi-Geraru fossil mandible. “We are confident in the age of LD350-1. We used multiple dating methods including radiometric analysis of volcanic ash layers, and all show that the hominin fossil is 2.8 to 2.75 million years old,” Erin N. DiMaggio of Penn State University said in a press release posted on Eureka Alert. Other fossils in the area include prehistoric antelope, elephants, a type of hippopotamus, crocodiles, and fish. These types of animals suggest that the habitat at the time was made up of mixed grasslands and shrub lands with trees lining rivers or wetlands. “We can see the 2.8 million-year-old aridity signal in the Ledi-Geraru faunal community. But it’s still too soon to say that this means climate change is responsible for the origin of Homo. We need a larger sample of hominin fossils and that’s why we continue to come to the Ledi-Geraru area to search,” added Kaye E. Reed of Arizona State University.

13th-Century Fortress May Have Belonged to Genghis Khan

March 4, 2015

MORIGUCHI, JAPAN—Japanese and Mongolian archaeologists have investigated a structure they say was commissioned for Genghis Khan by a close aide in 1212. The site, located in southwestern Mongolia, was first photographed from the air and surveyed in 2001 because its geographical features were similar to the landscape depicted in a medieval travel book. Surrounded by an earthen wall, the castle may have served as a military base when Genghis Khan was invading central Asia. Thirteenth-century Chinese ceramics were also recovered at the site. “We hope the discovery will be useful in ascertaining the history of the Mongolian Plateau between the thirteenth and fourteenth centuries,” team leader Koichi Matsuda of Osaka International University told The Asahi Shimbun. To read about the search for great khan's tomb, see "Genghis Khan: Founder of the Mongol Empire."

Was Rome Really a “City of Marble?”

March 4, 2015

LOS ANGELES, CALIFORNIA—Architectural historian Diane Favro of the University of California, Los Angeles, has employed advanced modeling software to reconstruct the city of Rome in its entirety over the period of the rule of Augustus Caesar, from 44 B.C. to A.D. 14. According to legend, Augustus boasted, “I found Rome a city of bricks and left it a city of marble.” Favro’s model uses a technique called procedural modeling that automatically regenerates as new information is added. The buildings are represented by massing models that are color-coded: marble buildings are pink, brick buildings are gray, and buildings under construction are yellow. She found that only a small proportion of the buildings in Augustan Rome were converted from brick to marble, and that they would have been difficult to see from ground level. “Given the literary descriptions and artwork, I thought these glittering marble temples on high would be very visible, but they were not,” she explained. She thinks that the movement of Carrara marble blocks from the northwest coast of Italy through the city probably caused congestion on the streets and created the illusion of a city of marble. “Because they saw construction taking place constantly, I believe people really did think that Rome had been transformed into marble. But in reality, the city did not greatly transform.” To read about how the construction of Rome's port fueled the empire's rise, see "Rome's Imperial Port."

Mercury in Ancient Fish Bones Linked to Rising Seas

March 3, 2015

KING SALMON, ALASKA—Alaska Dispatch News reports that the bones of cod recovered from a coastal archaeological site on Mink Island in Katmai National Park and Preserve contain high levels of toxic mercury. It is thought that the flesh of the fish, eaten by the people who lived at the site between 4,000 and 5,000 years ago, would have had significantly higher levels of the contaminant. The bones date to the early and mid-Holocene, when the climate was warming and rising seas were inundating the Bering Land Bridge and naturally occurring mercury in the dry or frozen land was dispersed into marine waters. The highest readings from the bones match or exceed present-day mercury levels in fish, which are elevated by mercury contamination from industrial activities around the world, according to Lawrence Duffy of the University of Alaska, Fairbanks. Mercury levels fell dramatically thousands of years later, once sea levels were stable. “The population, I’m comfortable in saying, would be more at risk than a population 1,000 years ago or 500 years ago when the levels had dropped,” Duffy said. For more on studies of ancient mercury contamination, see "Secrets of Life in the Soil."

18th-Dynasty Tomb Discovered in Luxor

March 3, 2015

CAIRO, EGYPT—A tomb dating to the 18th Dynasty has been discovered by a team from the American Research Center in the Gorna necropolis on Luxor’s west bank. The t-shaped tomb has two large halls and an unfinished small niche at one end. A side room has a shaft that “could lead to the burial chamber,” Minister of Antiquities Mamdouh el-Damaty told Ahram Online. The walls of the tomb, which was looted and damaged in antiquity, are decorated with paintings of hunting scenes and images of the tomb’s owner, a guard of Amun’s gate, and his wife in front of an offering table. Some of the scenes and hieroglyphic texts, including the name of the god Amun, had been erased. Soltan Eid, director of Upper Egypt Antiquities, explained that this may have been done during the reign of the monotheistic king Akhenaten.  For more on this period in Egyptian history, see "Hieroglyphs Shed Light on Akhenaten's Rule."

Shallow 17th-Century Grave Unearthed in Oxford

March 3, 2015

OXFORD, ENGLAND—The remains of a young woman were unearthed from a shallow grave in an area designated for gardens and buildings on historic maps. A Charles I silver shilling found near her shoulder is thought to have been placed on her eyes before she was put in a burial shroud held in place with pins. The coin was struck at the Tower Mint in 1640 or 1641 and suggests that the woman may have come from a prosperous family, but finding the remains of a wealthy person of the period buried outside a cemetery is highly unusual. “At present we have one young adult female burial that potentially dates from the English Civil War,” Carl Champness of Oxford Archaeology South told Culture 24. Archaeologists speculate that she may have died during the siege of Oxford, when a more formal burial may have been difficult. Radiocarbon dating and analysis of the bones could provide more information. To read in-depth about a site that tells the story of the evolution of England's culture over the course of thousands of years, see "The Scientist's Garden."

Lost City Found in Honduran Rainforest

March 3, 2015

FORT COLLINS, COLORADO—An international team of researchers, working with the Honduran government and its Institute of Anthropology and History, used Lidar technology to search La Mosquitia, an unexplored rain forest in eastern Honduras, famous for being the location of the legendary “White City,” or “City of the Monkey God.” Man-made ruins were spotted and confirmed by a team on the ground. “Through this amazing project we were able to use Lidar as a tool of discovery that resulted in the discovery of a lost world. We hope to continue this work in the future to more fully unravel this puzzle through archaeological excavation and ecological investigation,” said lead archaeologist Chris Fisher of Colorado State University. Artifacts from the site date from A.D. 1000 to 1400, but little else is known about them at this time. “We’re very excited to bring to life this lost culture,” Fisher said. It “will significantly change our understanding of this critical archaeological region.” To read more about the use of Lidar to explore sites in Central America, see "Lasers in the Jungle."
