Welcome to the Archeology forum. Were you out doing some gardening and dug up a relic from the distant past? would you like to know more about Ancient Egypt? Did you think Memphis was actually a city in Tennessee?
Well, for the answers to those and other burning questions you've found the right digs.
Our forum rules apply here too, if you haven't read them now is the time.

Radiocarbon chronology of Iron Age Jerusalem reveals calibration offsets and architectural developments
.Significance
Establishing a detailed absolute chronology in an actively inhabited urban environment is challenging. The key to the solution is to apply stringent field methodologies using microarchaeological methods, leading to dense, radiocarbon-dated stratigraphic sequences. In Iron Age Jerusalem, 103 14C measurements on samples from a range of contexts were used to reconstruct Jerusalem’s urban history. By wiggle matching against the calibration curve, a decadal resolution, not usually possible during the problematic 300-y-long Hallstatt plateau, was achieved. Results also revealed excursions in 14C concentration that were outside the ranges of the calibration curve, verified by a set of 100 calendar-dated tree rings. This field and lab approach could well be applicable to dating other urban contexts.
Abstract
Reconstructing the absolute chronology of Jerusalem during the time it served as the Judahite Kingdom’s capital is challenging due to its dense, still inhabited urban nature and the plateau shape of the radiocarbon calibration curve during part of this period. We present 103 radiocarbon dates from reliable archaeological contexts in five excavation areas of Iron Age Jerusalem, which tie between archaeology and biblical history. We exploit Jerusalem’s rich past, including textual evidence and vast archaeological remains, to overcome difficult problems in radiocarbon dating, including establishing a detailed chronology within the long-calibrated ranges of the Hallstatt Plateau and recognizing short-lived regional offsets in atmospheric 14C concentrations. The key to resolving these problems is to apply stringent field methodologies using microarchaeological methods, leading to densely radiocarbon-dated stratigraphic sequences. Using these sequences, we identify regional offsets in atmospheric 14C concentrations c. 720 BC, and in the historically secure stratigraphic horizon of the Babylonian destruction in 586 BC. The latter is verified by 100 single-ring measurements between 624 to 572 BC. This application of intense 14C dating sheds light on the reconstruction of Jerusalem in the Iron Age. It provides evidence for settlement in the 12th to 10th centuries BC and that westward expansion had already begun by the 9th century BC, with extensive architectural projects undertaken throughout the city in this period. This was followed by significant damage and rejuvenation of the city subsequent to the mid-eight century BC earthquake, after which the city was heavily fortified and continued to flourish until the Babylonian destruction.

Elisabetta Boaretto of the Weizmann Institute said: 'The resolution of c-14 was very bad – 200-300 years; it was impossible to distinguish anything else.
'With the work we've done in the City of David, we succeeded to reach a resolution less than 10 years, which is really something very very new and dramatic.'
