Because of the distortions and lies spread by fundamentalists about scientific dating there is a need for a centralized source of information on the topic.

Information about Simon Winchester's delightful biography of Smith, The Map That Changed the World is available at Tree-Ring dating is based on the principle that the growth rings on certain species of trees reflect variations in seasonal and annual rainfall.

Further, he proposed that wherever uncontorted layers were exposed, the bottom layer was deposited first and was, therefore, the oldest layer exposed; each succeeding layer, up to the topmost one, was progressively younger.

The Major Divisions of Geologic Time are shown here, arranged in chronological order with the oldest division at the bottom, the youngest at the top. Specifically, stratigraphy refers to the application of the Law of Superposition to soil and geological strata containing archaeological materials in order to determine the relative ages of layers.

It excludes contamination and weathering of travertines and makes possible more precise dating of thin deposits of secondary carbonates.

No web-based resource for this method is available.

These tests have consistently given the same ages for each of these objects.
