How acurate is carbon dating

Beside a slab of trilobites, in a quiet corner of Britain's Oxford University Museum of Natural History, lies a collection of ochre-tinted human bones known as the Red Lady of Paviland.In 1823, palaeontologist William Buckland painstakingly removed the fossils from a cave in Wales, and discovered ivory rods, shell beads and other ornaments in the vicinity.“This is the largest fortress found in all of Israel to date between the Canaanite cities…and it seems that it is essentially the largest fortress found in Israel until the days of King Herod,” states the website.He concluded that they belonged to a Roman-era witch or prostitute.“He did a good job of excavating, but he interpreted it totally wrong,” says Tom Higham, a 46-year-old archaeological scientist at the University of Oxford's Radiocarbon Accelerator Unit.A new Weizmann Institute study has discovered radiocarbon-dating evidence of the First Temple period under a tower in Jerusalem’s City of David that was previously dated to the Canaanite period.The findings, based on soil samples taken from under a seven-meter thick walled tower, shave nearly a thousand years from previous archaeological dating of the structure, which placed it c.

In addition to protecting the Gihon Spring, the massive fortification served as a sort of security barrier and permitted one entrance to the spring — “from the west only, from within the city,” according to the City of David website.

However, new findings by an interdisciplinary cooperative team of Israel Antiquities Authority archaeologists and Weizmann Institute scientists place the construction of the tower during the second half of the Iron Age — smack dab in the middle of the Israelite period, and much closer to the days of Herod than earlier suspected.

Discussions on the foundation and borders of Israelite-era Jerusalem are often rife with accusations of Jewish nationalism trumping evidential facts.

It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the Earth was created a very long time ago.

Further evidence comes from the complete agreement between radiometric dates and other dating methods such as counting tree rings or glacier ice core layers.

Back in the 1940s, the American chemist Willard Libby used this fact to determine the ages of organisms long dead.
