Dating artifacts done
Specialists in the field of astronomical research placed this solar eclipse as on 15 June 763 B. The Almanac belonging to Maya culture of Central America helped in dating several important sites accurately on the basis of astronomy.Astronomical data have been applied in the study of geological ice ages by calculating the curves for major fluctuation of solar radiation.This parallelism is formed due to trade relations, particularly wehen trade followed in both directions.For example, beads closely resembling those from the temple repositories at Cnoss and dating from C.1600 B.Specific locations can even be determined as the origins for many rare or uncommon pollens.Pollen can come in a variety of distinct shapes and sizes depending on the plant it is coming from.Pollen can also be collected from the inside of pottery such as pots and stone tools, trapped in the fabric of clothes, the the cracks of floors and walls, or on other archeological artifacts and features.
Pollen dating is done by comparing the pollen zones in different rock layers or strata, comparing older, deeper layers to newer ones on top.C were found in a late context (Period V) at Harappa. By noting the association of these beads it has been possible to trace a archaeological datum line across Indian sub-continent and Mesopotamia.This closely agrees with the fact that the seals from Indus Valley style from Ur, Kish and Tell Asmar and other sites fall within the range of 2500-1500 B. When a group or type of objects are found together under circumstances suggesting contemporanity they are said to be associated.But, even when the scientific methods of absolute dating are available, this method of dating has not lost its importance, as many a time we have to depend solely on relative dating.Even when the absolute dates are available, we have to supplement the information with relative dating.
