Understanding the age and period of existence of the excavated fossils and other organic objects will help the archaeologist to unravel human history and evolution in a scrupulous manner (Taylor 24).Archaeologists utilize one of the revolutionary methods called the radio carbon dating to determine the approximate age of the organic materials including plant and animal parts up to 50000 years (Long).The following will show that archaeoastronomy is far more than just an interdisciplinary field linking archaeology and astronomy.It merges aspects of anthropology, ethno-astronomy and even educational research, and is possibly better described as cultural astronomy.Significance Desmond Clark (1979) opinions that if radio carbon dating technique were not discovered, (Clark, 1979:7). Exploratory analysis of the international radiocarbon cross- calibration data: consensus values and interlaboratory error. According to Higham (1999) C14 method can be described as ‘the radio carbon revolution’ which has significantly impacted our understanding about evolution and also cultural emergence of human species. Once a hydration layer has been measured, it can be used to determine the relative ages of items or, in some circumstances, can be converted into an estimated absolute age. In order to transform the hydration rim value to a calendar age, the rate of the diffusion of water into the glass must be determined or estimated.
Hydration rims formed on artifacts can vary in width from less than one micron for items from the early historic period to nearly 30 microns for early sites in Africa (Michels et al. Formation of the hydration rim is affected not only by time but also by several other variables. Marks will be awarded for your own, creative thoughts on hard data. 3) The conclusion sums up the essence of your results and is basically the answer to the questions addressed in the introduction.

The most important of these are chemical composition and temperature, although water vapor pressure and soil alkalinity may also play a role in some contexts. The effects of these variables have often been summarized and will not be discussed further here (Michels and Tsong 1980; Friedman and Obradovich 1981; Freter 1993; Hull 2001; Stevenson et al., 1993, 1998, 2000; Friedman et al. 1999, Ridings 1996; see Skinner and Tremaine 1993 for additional references).
The hydration rate is typically established empirically through the calibration of measured samples recovered in association with materials whose cultural age is known or whose age can be radiometrically determined, usually through radiocarbon dating methods (Meighan 1976).
