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.

Since dinosaurs are thought to be over 65 million years old, the news is stunning - and more than some can tolerate.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.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.

He said that his team and the laboratories they employed took special care to avoid contamination.
