A decade ago, archaeologists made a grisly discovery when they unearthed two Neolithic mass graves at the sites of Bergheim and Achenheim in northeastern France. The pits contained severed limbs and human skeletons, evidence of excessive violence and mutilation that did not match normal Neolithic patterns. Some deceased individuals buried in other nearby graves, however, showed no signs of brutality. A new study has recently analyzed the chilling remains to try and reconstruct the identities of the individuals and determine why some were treated so cruelly, according to a statement released by the University of Oxford. Researchers conducted multi-isotopic analysis...

Science reports that recent analysis of an Inca recordkeeping device in the collection of the University of St. Andrews is upending what archaeologists previously thought about the pre-Columbian South American civilization. Hundreds of years ago, the Incas developed a unique system, using knotted cords known as khipus to record information such as dates, numbers, and transactions. These were typically made from long strands of llama or alpaca hair. It had been thought that the job of creating and maintaining these complicated tools was held by highly educated and elite administrative men who were among Inca society's upper echelon. A new...

Coinciding with the Pit Grave culture (4200-3600 years before our era), coming from Southern Europe, the Neolithic communities of the north-eastern Iberian Peninsula started a ceremonial activity related to the sacrifice and burial of dogs. The high amount of cases that are recorded in Catalonia suggests it was a general practice and it proves the tight relationship between humans and these animals, which, apart from being buried next to them, were fed a similar diet to humans'... The study analyses the remains of twenty-six dogs found in funerary structures from four sites and necropolises of the Barcelona region, and has...

nitrogen the Vikings left behind 11 September 2006 From New Scientist Print Edition. Discovering ancient settlements is often rather hit and miss, but the odds would be improved with a bit of chemical analysis. Plants growing over old sites of human habitation have a different chemistry from their neighbours, and these differences can reveal the location buried ruins. Plants mostly take in nitrogen from the soil as the isotope nitrogen-14, with just a dash of nitrogen-15. Plants growing above archaeological sites in Greenland, however, seem to have absorbed a larger dose of nitrogen-15. Rob Commisso and Erle Nelson from...
