The periods of relative quiet contribute only a small part of the record.
…The charge that the construction of the geologic scale involves circularity has a certain amount of validity….
The succession of organisms has been determined by a study of their remains embedded in the rocks, and the relative ages of the rocks are determined by the remains of organisms that they contain.” (Rastall, R.
If the laboratory results contradict the field evidence, the geologist assumes that there is something wrong with the machine date.
To put it another way, ‘good’ dates are those that agree with the field data.” (Mc Kee, B., , 1972, p.
E., “Pragmatism Versus Materialism in Stratigraphy,” , vol. 47.) “One might imagine that direct methods [radiometric dating] of measuring time would make obsolete all of the previous means of estimating age, but these new ‘absolute’ measurements are used more as a supplement to traditional methods [index fossils] than as a substitute.
Geologists put more faith in the principles of superposition and faunal succession than they do in numbers that come out of a machine.
Thus, the procedure is far from ideal and the geologic ranges of fossils are constantly being revised (usually extended) as new occurrences are found. ” (Raup, David M., “Geology and Creationism,” , vol. 21.) “The sedimentary rocks, by themselves, however, do not yield any specific time marks, setting aside the old law of superposition, which can provide relative age indication only in a restricted manner, and which is unfit for age correlations.
