The tables below present information on dated samples from New Zealand (South Pacific) and Trinidad (Southern Caribbean).
This is a classic “initial” Ciemna/Pradnik backed bifacial knife, (Keilmesser).
It was found as a stray find, decennia ago, at Neuburg at the Donau (Bavaria) in the heartland of the Central European Micoquian technocomplex.
Because of the somewhat short half-life of 14C, radiocarbon dating is not applicable to samples with ages greater than about 50,000 years, because the remaining concentration would be too small for accurate measurement.
Thermoluminescence dating: this method is associated with the effect of the high energy radiation emitted as a result of the decay or radioactive impurities.
It is widely used in dating fossils or archaeological samples containing organic material such as wood, charcoal, bone, shells, etc.
It is not used to date rocks or other inorganic material.
The prefix identifies the laboratory that processed the sample.
The 'Wk' prefix shown here indicates that these samples were processed at the University of Waikato Radiocarbon Dating Laboratory.
Carbon-14 dates usually appear to be reasonably accurate whenever they can be checked against historical records.
For example, when the Dead Sea Scrolls were dated, three methods could be used: 1) Dates written in the documents themselves (like the date at the start of a letter) 2) Paleography, which uses the style of script used to write documents to date them, and 3) Carbon-14.
Carbon-14 dating cannot be applied to materials that have no C dates are less than that figure.
