Senior research scientist Alexander Cherkinsky specializes in the preparation of samples for Carbon-14 testing.He directed the pretreatment and processing of the dinosaur bone samples with the Accelerator Mass Spectrometer, though he did not know the bones were from dinosaurs, and he signed the reports.
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.
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.
Schweitzer herself wonders why these materials are preserved when all the models say they should be degraded.
That is, if they really are over 65 million years old, as the conventional wisdom says. A lone femur bone was excavated in 2004 in Cretaceous clay at 47 6 18N by 104 39 22W in Montana by the O. Miller team in 2005 to retrieve samples for C-14 testing. Collagen: Proteins that are the main component of connective tissue.
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.
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).
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.
Despite being simple test results without any interpretation, they were blocked from presentation in conference proceedings by the 2009 North American Paleontological Convention, the American Geophysical Union in 20, the Geological Society of America in 20, and by the editors of various scientific journals.

Detwiler; in 108 MA Cretaceous sandstone - identified by Dr. The "Modified Longin Method" is the normal purification method for bone collagen. Libby, the discoverer of Radiocarbon dating and Nobel Prize winner, showed that purified collagen could not give erroneous ages.
