Arsenic accumulation on the bones in the Early Bronze Age İkiztepe Population,Turkey

In this study, arsenic, copper and lead content of a group of human and animal bones recovered from the Early Bronze Age ?kiztepe site have been analyzed using ICP-MS method. Average arsenic value of 90 femur bones of a human was found to be 15.0 ± 5.79 ppm which was varied among age and sex groups, and among species. Origin of arsenic accumulation in bones was diagenetic because overall the groups were highly variable. The distribution of metallic items among the burials had a big affect on the arsenic uptake of the bones. Copper and lead values supported the diagenetic arsenic accumulation in the bones as well. Their values on the bones were not as high as those for the individuals involved in metal working activities in the ancient world. Judging from these data, it is concluded that ?kiztepe people did not produce the manufactured metallic items using arsenical copper but might have been imported from the other sites.     

European Neanderthal stone hunting weapons reveal complex behaviour long before the appearance of modern humans

Stone weapon points constitute a major innovation appearing at the end of the Middle Pleistocene in Europe, Africa and the Near East; that is, among both sapiens and Neanderthal populations. The microscopic analysis of the stone weapons used by Neanderthal groups in Atlantic southern Europe suggests that this technology was widespread and became a recurrent behaviour within organised strategies developed by these societies. In this southern region of Europe, stone weapon hunting technology appears at an early time (about 150 ka, OIS 6) and is associated with the hunting of large mammals. This behaviour can be recognised in a geomorphologically complex region and at a time of great environmental change (OIS 6–5–4). The fact that these innovations were used by European Neanderthals long before the spread of anatomically modern humans in the area is of great evolutionary significance.     

A possible fatal wounding in the prehistoric Pacific Islands

This paper reports two cases of prehistoric interpersonal violence from Taumako Island, southeast Solomon Islands. The first case is a young child with a bone point found in situ in a lower lumbar vertebra. It is concluded that this child most likely died as the result of the injury. The second case is a male of advanced age with a well‐remodelled depression fracture on the frontal bone of the skull. This individual also has a remodelled penetrating wound to the left iliac crest of the pelvis. Warfare is thought to have been endemic in much of the Solomon Islands before European arrival. However, besides the two cases reported here there is little other evidence of trauma in the Taumako population. The young child is the first case of an in situ weapon reported from the prehistoric Pacific Islands. Copyright © 2000 John Wiley & Sons, Ltd.     

Cranial weapon injuries from Anglo-Saxon dover

Two adult male skeletons from Buckland Dover, dated to the pagan Anglo-Saxon period, displayed evidence of cranial weapon injury. In one case (SK 348) the injury, probably inflicted by a sword, showed no evidence of healing. The other (SK 303b), possibly an axe injury, appears to have been survived. The nature of the traumata, blade injuries, suggest that they were inflicted in battle rather than the result of a street brawl. However, neither skeleton was buried with weapons, suggesting that they may have been seized by the attackers on the battlefield.
