ABSTRACTWe investigate the link between the consumption of foodstuffs, excavation of a large pit, and disposal of waste at the Tillar Farms site (3DR30), southeast Arkansas, using refit and oxygen isotope analyses of well-preserved freshwater mussel shells from Feature 1. Only 0.13% of 7,408 valves analyzed were unidentifiable to species.The refit analysis produced 460 refits across 23 species and strongly indicates that the shell midden represents a single episode of shellfish gathering, consumption, and discard. Oxygen isotope analysis of five randomly selected shells are used as a test of the refit results. δ18O values from the five archaeological shells are compared to modern control samples of live-collected specimens from Bayou Bartholomew in winter of 2011. Refit analysis suggests the accumulation of mussel shells occurred quickly, likely as a result of one collection, consumption, and discard event. δ18O values suggest this activity took place during a single winter season. 相似文献

A skull found in a burial cave near Jericho with evidence of craniectomies dating approximately 5500 years ago had signs of frontal sinusitis and intracranial infection. The location of the three craniotomies in the frontal bone of this skull and evidence of the infection bursting from the sinus intracranially suggest that this is the oldest known cranial surgery performed due to symptoms of a medical aetiology : epidural infection. 相似文献
