This consciously excludes ruins of limited height, roads and statues. Bridges may be included if they otherwise fulfill the above criteria. Dates for many of the oldest structures have been arrived at by radiocarbon dating or dendrochronology and should be considered approximate. If the exact year of initial construction is estimated, it will ...
Radiocarbon dating tests on three samples of charred hickory nut remains found at the site produced a mean age of 2402 BP, indicating that the site was occupied during the Early Adena period. [ 8 ] A restored ceramic vessel, as well as portions of a rim, the base, and a lug handle from another vessel found on the site, are on display at the ...
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby.
Willard Frank Libby (December 17, 1908 – September 8, 1980) was an American physical chemist noted for his role in the 1949 development of radiocarbon dating, a process which revolutionized archaeology and palaeontology.
Starting from the pulse around the year 1963 (see figure), atmospheric radiocarbon relative abundance decreased by about 4% a year. So in bomb pulse dating it is the relative amount of 14 C in the atmosphere that is decreasing and not the amount of 14 C in dead organisms, as is the case in classical carbon dating.

The old wood effect or old wood problem is a pitfall encountered in the archaeological technique of radiocarbon dating. A sample will provide misleading or confusing results if materials of different ages are deposited in the same context. Stratification is not always clear-cut in practice. In the case of dating megalithic tombs, indirect ...
Radiocarbon dating of the artefacts and the remains of Anzick-1 indicate an age of around 12,990–12,840 years Before Present for the burial. [1] Skull fragments of a second individual (Anzick-2), a child of around 6-8 years of age, were also found at the site 6 metres (20 ft) east of Anzick-1, which lack ocher staining.
