Dating a rock

This failure leaves the method vulnerable to circularity.” (Stanley, Steven M., Warron O.

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….

Scientists have determined the relative times of appearance and disappearance of many kinds of organisms from the location of their fossils within the sedimentary rock layers.” (Glenco, 1994, pp. 714.) “The procession of life was never witnessed, it is inferred.

By doing so, we are guilty of circular reasoning if we then say the fossil record supports this theory.” (West, Ronald R., “Paleontology and Uniformitarianism,” vol. 216.) “It cannot be denied that from a strictly philosophical standpoint geologists are here arguing in a circle.

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.

(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.

Since these processes occur to an extent in virtually all sedimentary systems, stratigraphic disorder at some scale is probably a common feature of the fossil record.” (Cutler, Alan H., and Karl W.

Plessa, “Fossils out of Sequence: Computer Simulations and Strategies for Dealing with Stratigraphic Disorder,” vol. 227.) “Contrary to what most scientists write, the fossil record does not support the Darwinian theory of evolution because it is this theory (there are several) which we use to interpret the fossil record.

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.

Ever since William Smith at the beginning of the 19th century, fossils have been and still are the best and most accurate method of dating and correlating the rocks in which they occur. 49.) “Are the authorities maintaining, on the one hand, that evolution is documented by geology and, on the other that geology is documented by evolution? Stratigraphy cannot avoid this kind of reasoning, if it insists on using only temporal concepts, because circularity is inherent in the derivation of time scales.” (O’Rourke, J.

The periods of relative quiet contribute only a small part of the record.
