Radiocarbon dating controversy
Knowing that small concentrations of collagen can attract contamination, they compared precision Accelerator Mass Spectrometry (AMS) tests of collagen and bioapatite (hard carbonate bone mineral) with conventional counting methods of large bone fragments from the same dinosaurs. Mary Schweitzer, associate professor of marine, earth, and atmospheric sciences at North Carolina State University, surprised scientists in 2005 when she reported finding soft tissue in dinosaur bones.These, together with many other remarkable concordances between samples from different fossils, geographic regions and stratigraphic positions make random contamination as origin of the C-14 unlikely". She started a firestorm of controversy in 20 when she reported that she had sequenced proteins in the dinosaur bone.So when he received another bone sample from the Paleochronology group, he returned it to sender and sent an email saying: "I have recently become aware of the work that you and your team have been conducting with respect to radiocarbon dating of bone.The scientists at CAIS and I are dismayed by the claims that you and your team have made with respect to the age of the Earth and the validity of biological evolution.This was news to him, and contradicted prior statements and documents from the university.He is currently seeking relief in a legal action for wrongful termination and religious discrimination by California State University Northridge (CSUN).
The university claimed his appointment at had been temporary and claimed a lack of funding for the position.
Members of the Paleochronology group presented their findings at the 2012 Western Pacific Geophysics Meeting in Singapore, August 13-17, a conference of the American Geophysical Union (AGU) and the Asia Oceania Geosciences Society (AOGS).
Since dinosaurs are thought to be over 65 million years old, the news is stunning - and more than some can tolerate.
No, his objection was that the Paleochronology group was using the reports as evidence that dinosaurs lived thousands, not millions, of years ago. A manager of a commercial laboratory that does Carbon-14 dating, Beta Analytic Inc., reviewed a poster display of the dinosaur data and discussed it with a member of the Paleochronology group.
So I asked him 3 times over 3 weeks what is the right conclusion to draw from the test results they provided us; then I asked his entire scientific staff. Her interest led us to propose that her company perform a Carbon-14 test on a T-rex bone we acquired.
