"This tomb was in use during the Neolithic period and radiocarbon dates place its use between 3,800 - 3,600 BC. The first excavation of Poulnabrone Dolmen was in 1986 and then again in 1988 by Ann Lynch. During this excavation, one portal stone was replaced, and the team excavated the chamber, portico, and cairn. The remains of up to 22 individuals from the Neolithic were found. Sixteen adults, six children, and one newborn (from the Bronze Age) were among the remains. Their bodies were not cremated. Only one adult was over the age of 40 while most died before they reached 30. Most of the children were between the ages of five and fifteen. The skeletal remains show evidence of arthritis. The tip of a flint or chert projectile point was found embedded in the hip of one individual. Two other healed fractures, one skull and one rib, were also found. Dental wear analysis shows evidence for the consumption of stone-grounded cereals. Also found in the burial chamber was a polished stone axe, 2 stone beads, a decorated bone pendant, a fragment of a mushroom-headed bone pin, 2 quartz crystals, several shards of coarse pottery, and a number of arrowheads and scrapers. Grykes are crevices in the limestone that were then filled with remains. Chamber and grykes also were filled with the bones of various large and small animals."
