Amino acid dating fossils why arent we dating scam
The rate at which racemization proceeds depends on the type of amino acid and on the average temperature, humidity, acidity (p H), and other characteristics of the enclosing matrix.Also, D/L concentration thresholds appear to occur as sudden decreases in the rate of racemization.These effects restrict amino acid chronologies to materials with known environmental histories and/or relative intercomparisons with other dating methods.Temperature and humidity histories of microenvironments are being produced at ever increasing rates as technologies advance and technologists accumulate data.Because the rate of amino acid racemization is controlled by the temperature experienced by the fossil since burial (rather than when it was living), an evaluation of site temperature is required for geochronological interpretation.To minimize the effect of seasonal and diurnal temperature fluctuations, samples should remain buried at least 1 m and preferably 2 to 3 m throughout their post-depositional history.
Chronological sequence is all that is really required.

You may find it useful for the clear definitions, and for excellent links on a variety of topic.
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.
A few examples of such lies are presented at the very bottom of this page.
