It was argued that this evidence could not support a young age for the earth. Harold Coffin carried out a detailed investigation of these petrified forests and discovered that they strongly support the catastrophic model.As many of the trees stand upright in an apparent position of growth, it was accepted that they were the remains of an actual forest. Closer examination reveals that the petrified trees have no bark with side branches and root stocks ripped off.To me it has been a real eye opener to see all the processes that are taking place and their potential influence on radiometric dating.Radiometric dating is largely done on rock that has formed from solidified lava.In places, the vertical separation is actually very small; the new layer lying just above the stumps of the older layer.Close examination of the strata reveals typical evidence of sorting of layers, which tend to show reverse grading with the coarser material on top.This is inconsistent with trees being covered with ash while in a position of growth.

Technical details on how these dates are calculated are given in Radiometric dating. As with any experimental procedure in any field of science, these measurements are subject to certain "glitches" and "anomalies," as noted in the literature.The latest high-tech equipment permits reliable results to be obtained even with microscopic samples.Radiometric dating is self-checking, because the data (after certain preliminary calculations are made) are fitted to a straight line (an "isochron") by means of standard linear regression methods of statistics.These long time periods are computed by measuring the ratio of daughter to parent substance in a rock and inferring an age based on this ratio.This age is computed under the assumption that the parent substance (say, uranium) gradually decays to the daughter substance (say, lead), so the higher the ratio of lead to uranium, the older the rock must be.One of the most popular dating methods, carbon-14 (14C), is used for dating plant or animal remains.
