(from oldest to newest CASE STUDY How Old Is Stonehenge? Approximately eight miles north of Salisbury, Wiltshire, England, stands a large circular stone surrounded by an earthwork. This prehistoric structure is known throughout the world as Stonehenge. Its name is derived from the Old English word hergen, referring to something hung up in the case of the mon ment, this name refers to the large horizontal lintel stones. The SULLIVAN.WOODBURY monument consists of an outer ring of sansen stones. surrounding two inner circles of bluestones. The first and third circles are adorned with the familiar stone lintels The entire structure is surrounded by a ditch and bank Just inside the bank are 56 pits, B ed the Aubrey Holes after their discoverer. The ave been alled shortly after their excavation.

Excavations at the hase of the di some sort of massive art If this umber of antiers, which bore signs of heavy use. The conclusion is accurate, it seems likely that them antlers could have been used by the builders as picks or might have been used as a temple for sky worship rakes. The fact that no primary sill was discovered benes Corina Dillion is interested in the antlers suggests that they were buried in the ditch of the structure. Excavations shortly after its completion. Another researcher number of unshed antlers antler times, Corbin, using an archaeological markings appro Carbon 14 dating methods were used previously claimed that the mean date for the co of the Stonehenge artifacts Cartoon 14 is one of three of the ditch was 2950 nc. A sample of nine age e carbon isotopes found in Earth's atm Carbon 12 antlers excavated from makes up 99% of all the carbon dierside in the air. Virtually mean of 30331 IC. with standard deviation all the remaining 1% is compe of carbon 13. By far, the asume that the ages are norm rarest form of carbon botope fou in the atmosphere is obvious outliers. At an a - OUS sig arbon 14. any reason to dispute Corbin's daim? The ratio of carbon 14 to carbon 12 remains constant Four animal bone samples were in living organisms However, once the organism dice minal.
