University of arizona carbon dating dinosaur bones
Austin Long, professor of geochemistry at the University of Arizona, informed Miller that there was no collagen (a protein which is the source of most of the carbon in bones) in the samples and that large amounts of shellac and other contaminants were present.
Miller indicated that he wanted the samples dated regardless.
Subsequently, several of the bone fragments were submitted to the University of Arizona's Laboratory of Isotope Geochemistry for radiocarbon dating.
CRSEF "also arranged the Arizona testing by not revealing its origins" (Lafferty 1991:2B).
The process of fossilisation replaces the original organic matter with minerals, some of which may contain carbon, but carbon derived not from the fossil but from the environment, and this process can take place over a very long period and the resulting minerals will always be in dynamic equilibrium with their environment.
So what has this to do with Hugh Miller and creationist lies?
James King, Director of the Carnegie Museum, says Hugh Miller and his party identified themselves as chemists who wanted to do some analyses of the chemical composition of the fossils.
The minerals in fossils are replacements for the original material, not necessarily the products of it.
Well, yes, that was a fortuitous conincidence, wasn't it! It was an even more elaborate hoax than the Paluxy hoax.
Bear in mind that Hugh Miller is a leading member of the Creation Research, Science Education Foundation (CRSEF). Lepper explain in his National Center for Science Education, article, "Radiocarbon Dates for Dinosaur Bones? Bradley Lepper is the Curator and Site Archaeologist for the Ohio Historical Society's Newark Earthworks and Flint Ridge State Memorials.
The dating technique is based on three facts: C in the general background is very small to begin with, being only about one atom in one trillion.
This means that a reasonably large sample is needed to begin with and, more importantly, it doesn't take long, no matter how large the sample, for the number of C dating is only useful up to about 50,000 years and decreasingly so as that age approaches.
