wells gradually became contaminated with seawater, forcing the inhabitants to abandon their homes. A stone semicircle, containing seven 600 kg (1,300 lb) megaliths, has been found. The stones have cup marks carved into them and are arranged around a freshwater spring, which suggests that they may have been used for a water ritual. Ten flexed burials have been discovered, both inside the houses and in their vicinity. The skeletons of a woman and child, found in 2008, have revealed the earliest known cases of tuberculosis. Bone fish-hooks and piles of fish bones ready for trade or storage point to the importance of marine resources. The men are thought to have dived for seafood, as four skeletons with ear damage have been found, probably caused by diving in cold water. Anthropomorphic stone stelae have been found. The lithics include arrowheads, sickle-blades, and axes. An excavation was mounted by the University of Haifa on October 1, 1987. A complete human burial, in an excellent state of preservation, was discovered under 10m of water on October 4 with the skeleton oriented in a flexed position and laid on her right side. Subsequent carbon dating of plant material recovered from the burial placed the age of the site at 8000 +-200 years. Animal bones and plant remains also have been preserved. Animal bones come mainly from wild species. The plant remains include wild grape, poppy, and caraway seeds. Granary weevils indicate the presence of stored grain. Pollen analysis and the remains of marsh plants indicates the local presence of swamps.
