Engineers Investigate Rock Fall at Parthenon

ATHENS, GREECE—Part of the flat-topped rock that supports the 2,500-year-old Parthenon is crumbling, according to engineers from the Central Archaeological Council who examined the Acropolis after the fall of a boulder of “considerable size” last January. According to Phys.org, the team found “instability over a wide area,” probably caused by rainwater drainage from the old Acropolis museum. The southern slope of the hill that supports the Parthenon will have to be reinforced. To read about how ancient Greeks viewed their own past, see ARCHAEOLOGY's "Monuments and Memory."  

Moa Hunter Site Damaged in New Zealand

CHRISTCHURCH, NEW ZEALAND—The New Zealand Herald reports that a 600-year-old moa-hunter occupation site was disturbed in 2011 during work to clear and rebuild an earthquake-damaged home. “The site has played a crucial role in developing ideas about the origins of Maori culture and the relationship between moa hunters and classical Maori,” Heritage New Zealand summarized for Christchurch District Court. The two companies involved in the work had not submitted their plans to Heritage New Zealand, which is in charge of monitoring construction and minimizing damage to the historical record. “Although it is not possible to determine the exact extent of damage caused by the excavations for the foundations of a new dwelling, it is clear from the test trenches that the excavations for the gravel and concrete pad have cut through the in situ layer, disturbing at least one feature in the process,” the report concluded. 

Franklin Shipwreck Identified as HMS Erebus

OTTAWA, CANADA—The shipwreck discovered last month in the Arctic has been identified by Parks Canada underwater archaeologists as HMS Erebus, one of the ships in Sir John Franklin’s doomed 1845 expedition to find the Northwest Passage from the Atlantic Ocean to Asia. Franklin commanded the enterprise from the Erebus, but it is not known if he was buried at sea before the ship was abandoned in 1847. “Without a doubt it is the most extraordinary shipwreck I’ve ever had the privilege of diving on,” lead archaeologist Ryan Harris told CBC News. He and his diving partner did not enter the ship, but they could see below decks through exposed beams and old skylights. A total of seven dives have been conducted to date. To read about the discovery of HMS Investigator, the doomed vessel dispatched to search for HMS Erebus and HMS Terror, see ARCHAEOLOGY's feature "Saga of the Northwest Passage."  

Twin Basketmaker Villages Discovered in Arizona

PETRIFIED NATIONAL FOREST PARK, ARIZONA—Two villages estimated to be 1,300 years old have been discovered in the high desert of northern Arizona. The sites, recently acquired by Petrified Forest National Park, feature walls and floors lined with slabs of sandstone. “Last year we found a large habitation site, and this summer we found a match, less than a mile away, a site that has dozens and dozens of different features. We have now two large groups of pit house structures, both of them with probably more than 50 structures associated with them,” park archaeologist William Reitze told Western Digs. He and his team also recovered ceramics and stone points from the late Basketmaker period, when the residents of the village were transitioning from nomadic foraging to a more sedentary society based upon agriculture. “These sites are often in large sand dunes, but there is no rock there. So any kind of slab at all that you find out there was brought in by people,” Reitze explained. To read more about the prehistory of the Southwest, see ARCHAEOLOGY's "Who Were the Anasazi?"

Wild Chimpanzees Observed Transmitting Behavior Socially

ST ANDREWS, SCOTLAND—The Sonso chimpanzee community living in Uganda’s Budongo Forest has been observed passing a new natural behavior from individual to individual by a team made up of scientists from the University of St. Andrews, the University of Neuchâtel, Anglia Ruskin University, and the Université du Quebec. This is the first time that social transmission has been documented in a wild community. The chimpanzees developed variants of using “leaf-sponges,” which are folded leaves used for drinking water. The variations included adding moss to the leaves to make a drinking device, and reusing a discarded leaf sponge. Science Daily reports that by using a technique called network-based diffusion analysis, the researchers estimated that each time a “naïve” chimpanzee observed moss-sponging, this individual was 15 times more likely to develop the behavior. Thibaud Gruber of the University of Neuchâtel explained that such social learning probably originated in an ancestor common to great apes and humans. “This study tells us that chimpanzee culture changes over time, little by little, by building on previous knowledge found within the community. …In this respect, this is a great example of how studying chimpanzee culture can help us model the evolution of human culture. Nevertheless, something must have subsequently happened in our evolution that caused a qualitative shift in what we could transmit, rendering our culture much more complex than anything found in wild apes. Understanding this qualitative jump in our evolutionary history is what we need to investigate now,” he said. To read more about chimpanzee tool use, see ARCHAEOLOGY's "Cultured Cousins?"  

Ancient Earthquake Damage Found in Israel

HAIFA, ISRAEL—A team led by Michael Eisenberg of the University of Haifa has uncovered the northern section of the first-century basilica at Hippos, a center of Greek and Roman culture located near the Sea of Galilee. The roof of the structure collapsed during an earthquake in 363, killing the occupants, whose skeletons were found beneath the rubble. Among the victims was a woman who had been wearing a gold dove pendant. Eisenberg and his team used coins to date the collapse and attribute it to the earthquake. “The latest of those coins dated to 362 A.D. About three feet above the debris of the basilica we found Early Byzantine rooms dated by dozens of coins in the floors themselves to 383 A.D.,” Eisenberg told Discovery News. “It shows that major parts of the city were totally destroyed and neglected for a period of about 20 years.” Hippos was finally destroyed by an earthquake in 749.

Remote Sites Yield Evidence of Early South Americans

ORONO, MAINE—New research is focusing on hunter gatherers who colonized South America at the close of the last Ice Age. Kurt Rademaker of the University of Maine has found a rock shelter high in the Andes that was inhabited 12,400 years ago. “The [Pucuncho Basin] has fresh water, camelids, stone for toolmaking, combustible fuel for fires and rock shelters for living in,” he told Nature News. “Basically, everything you need to live is here. This is one of the richest basins I’ve seen, and it probably was then too.” And scientists are carefully examining the stone tools from South America’s Paleo-Indian sites because many of them are made from stone not available in the area where they were found. “What we’re seeing is that 12,000 years ago or more, these groups already had networks, knew the landscape and moved between the coast and the interior,” said César Méndez of the University of Chile.

Students Unearth Sweat Lodge at Cahokia Mounds

SAINT LOUIS, MISSOURI—Students from Saint Louis University discovered three partial house basins and the entire basin of a burned sweat lodge during their field school at the Fingerhut Tract of Cahokia Mounds State Historic Site this summer. The sweat lodge measures nine feet in diameter and would have had a domed roof. Charcoal within the sweat lodge will be radiocarbon dated. The students also uncovered many microdrills. “This area of Cahokia Mounds may have been involved in craft specialization for the prehistoric chiefdom,” said principal investigator Mary Vermillion.

4,000-Year-Old Ritual Site Discovered in Poland

WARSAW, POLAND—A 4,000-year-old ritual site has been unearthed on a hilltop in northeastern Poland. Fragments of decorated cups and bowls made by the Bell Beaker culture were found surrounded by burned bones and a fragment of an amber bead. A second amber object was found nearby. “Amber was an exotic and prestigious material for the Bell Beaker communities, and never before found in Podlasie. These discovered ornaments are among the oldest objects of this type in the region,” archaeologist Dariusz Manasterski of the University of Warsaw told Science & Scholarship in Poland. Stone tools, including an adze, a fragment of a curved blade, and fragments of a dagger were found, along with arrowheads and other blades and knives made of flint. “The entire ritual deposit is an exceptional find in central Europe. It contains one of the richest collections of objects usually found in the elite graves in Western Europe from this period,” he added. Understanding how those artifacts traveled so far east requires further investigation. To read about 4,000-year-old Bronze Age rituals in Eastern Europe, see "Wolf Rites of Winter."  

Canoe & Climate Shed Light on Polynesian Sailing Technology

AUCKLAND, NEW ZEALAND—Two new studies published in the Proceedings of the National Academy of Sciences shed light on how Polynesian seafarers colonized the islands of the Pacific Ocean. Lead author Dilys Amanda Johns of the University of Auckland described a 600-year-old canoe discovered in 2012 near the Anaweka River on New Zealand’s South Island. The nearly 20-foot long section of a vessel estimated to have been 45 feet long was constructed with wood from trees native to New Zealand, but in a manner similar to a canoe of the same age that was discovered in the Society Islands. There is also a turtle carved in relief on the hull just above the water line, which is a common motif among the Polynesians, but is rare in art from New Zealand. The second study, led by Ian Goodwin of Macquarie University, created a model of the paleoclimate in 20-year increments, in order to evaluate whether or not Polynesian vessels, which were not capable of sailing into the wind at the time of colonization, would have had to travel into the wind to head east. The model suggests that shifting climate conditions would have opened up times when the Polynesians could have traveled with the wind at their backs. “Our reconstructed sailing conditions during the period of East Polynesian colonization would have enabled all of the known colonizing routes, and others,” Goodwin told Science. The window for sailing to New Zealand would have closed before 1300, however. “There is a timing discrepancy,” commented Johns. She thinks the canoe, which has been radiocarbon dated to 1400, may have been built by New Zealanders with techniques handed down from the time of Polynesian contact.
