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.She wrote back: Thanks for considering our service in this project.We wish you well in your research but must choose to opt-out of the analysis.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 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.
Since you have identified it as T-rex, and these are known to be extinct for 50 million years, it is beyond the limit of our dating.
Mark Armitage served as the Manager for the Electron and Confocal Microscopy Suite in the Biology Department at California State University Northridge from January 2010 to February 2013.
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.
From 2007 through 2011 the Paleochronology group had 11 dinosaur bone samples carbon dated by the Center for Applied Isotope Studies at the University of Georgia, and for good reason.
