Apart from very ‘modern’ examples, which are really archaeology, I can think of no cases of radioactive decay being used to date fossils.” (Ager, Derek V., “Fossil Frustrations,” , vol. 425.) “The larger part of the Phanerozoic time scale…relies on a construction where stages are first scaled ‘geologically’ with biostratigraphic compositing techniques, and then stretched in linear time using key radiometric dates. E., “Pragmatism Versus Materialism in Stratigraphy,”, vol. 53) “A great deal has changed, however, and contemporary geologists and paleontologists now generally accept catastrophe as a ‘way of life’ although they may avoid the word catastrophe.In fact, many geologists now see rare, short-lived events as being the principal contributors to geologic sequences….

Addicott, and Kiyotaka Chinzei, “Lyellian Curves in Paleontology: Possibilities and Limitations,”, vol. 422.) “Often, the layers of rock can be dated by the types of fossils they contain….Any sequence in which an older fossil occurs above a younger one is stratigraphically disordered.Scales of stratigraphic disorder may be from millimeters to many meters.(Some of the following quotes are as cited in Morris, 1997 and Snelling, 1990).The series of quotes begins with a vivid illustration of this circular reasoning in action.(Welles, Samuel Paul, “Paleontology,” In some cases darwinists have recognized circularity as a typical problem in evolutionary models and worked to avoid it.

“To test this idea, we matched earliest Cambrian records of carbon isotope variability from Siberia, Mongolia, and China with a Moroccan record constrained by five radiometric ages from interbedded volcanic ashes.This time interval was from 542-520 million years ago.This approach avoids the circularity associated with using fossils to correlate rocks, and then using those correlations to infer biological patterns…” (“Cambrian Explosion: New Timeline for Appearances of Skeletal Animals in Fossil Record,” , Nov.The only chronometric scale applicable in geologic history for the stratigraphic classification of rocks and for dating geologic events exactly is furnished by the fossils.Owing to the irreversibility of evolution, they offer an unambiguous timescale for relative age determinations and for world-wide correlations of rocks.” (Schindewolf, O.It is almost the first thing I teach my first-year students. al., : Biostratigraphy: Time Scales from Graphic and Quantitative Methods,” , 2004, p. The rocks do date the fossils, but the fossils date the rocks more accurately.
