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.

Researchers have found a reason for the puzzling survival of soft tissue and collagen in dinosaur bones - the bones are younger than anyone ever guessed.

Carbon-14 (C-14) dating of multiple samples of bone from 8 dinosaurs found in Texas, Alaska, Colorado, and Montana revealed that they are only 22,000 to 39,000 years old.

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.

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.

Consequently, we are no longer able to provide radiocarbon services in support of your anti-scientific agenda.

I have instructed the Radiocarbon Laboratory to return your recent samples to you and to not accept any future samples for analysis."Notice that he did not say the radiocarbon reports of the dinosaur bone samples were inaccurate.

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.
