The rings in a non-living specimen can be counted to determine the number of years the specimen spans.SYNONYMS OR RELATED TERMS: coring CATEGORY: artifact DEFINITION: A black or gray zone in the interior cross-section of a vessel wall, usually associated with incomplete removal of carbonaceous matter from the clay during relatively low-temperature firing; not to be confused with black coring at high temperatures, which results from trapped gases and may lead to bloating SYNONYMS OR RELATED TERMS: nucleus CATEGORY: lithics DEFINITION: A piece of stone used as a blank from which flakes or blades were removed by prehistoric toolmakers.Usually it was the by-product of toolmaking, but it may also have been shaped and modified to serve as an implement in its own right. The core is undisturbed and the sediment contacts, soil boundaries, and structures are intact and can be described accurately.The following article is abstracted from The Biblical Chronologist Volume 5, Number 1. The science of constructing chronologies from tree rings is called dendrochronology. Modern trees are known to produce one growth ring per year. (The idea that ancient trees grew more than one ring per year will be discussed below.) Therefore, by coring a living tree and counting rings from the present backwards, it is possible to determine the year in which each ring grew. The bristlecone pines in the White Mountains of California live to extremely old ages, some in excess of 4,000 years.The University of Arizona dendrochronology lab sports a (no longer living) specimen which contains over 6,000 rings.By matching ring-width patterns in a specimen of known age (starting with living specimens) to ring-width patterns in an older specimen, the proper placement of the older specimen is determined.
