Biostratigraphy: One of the first and most basic scientific dating methods is also one of the easiest to understand.

Layers of rock build one atop another — find a fossil or artifact in one layer, and you can reasonably assume it’s older than anything above it.

A comprehensive rebuttal of the magnetism-decay method of dating was recently published in the Journal of Geological Education by G. In reaction to Dalrymple's criticisms, Barnes has written a four-page response for the Institute of Creation Research's Impact series entitled "Earth's Magnetic Age: The Achilles Heel of Evolution," which begins with these words: "There is nothing more devastating to the doctrine of evolution than the scientific evidence of a young earth age.

That evidence is provided by the rapid depletion of the energy in the earth's main magnet, its electromagnetic dipole magnet in the conductive core of the earth." Creationists who believe in an old earth have also attacked Barnes's model because it limits the earth's age to a maximum of ten thousand years.

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.

In contrast with the radiocarbon system of dating, the magnetism system was developed and refined solely by creationists because of its claim to limit the earth's age to ten thousand years.In fact, for the first decade of its existence noncreationist scientists never even took notice of Barnes's proposal.It wasn't until 19 when the creationist controversy erupted in the classrooms, when the Arkansas and Louisiana creationist legislation was being challenged in the courtrooms, and when scientific societies were beginning to have papers attacking creationism at their annual conventions that Barnes's ingenious method of dating the earth by its magnetism was brought to the attention of the scientific world. Geological Survey as an expert in radioactive dating, especially the potassium-argon method.When it comes to determining the age of stuff scientists dig out of the ground, whether fossil or artifact, “there are good dates and bad dates and ugly dates,” says paleoanthropologist John Shea of Stony Brook University.The good dates are confirmed using at least two different methods, ideally involving multiple independent labs for each method to cross-check results.Paleontologists still commonly use biostratigraphy to date fossils, often in combination with paleomagnetism and tephrochronology.
