Mark was suddenly terminated by the Biology Department when his discovery of soft tissues in a Triceratops horn was published in Acta Histochemica.

The university claimed his appointment at had been temporary and claimed a lack of funding for the position.

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.

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.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.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.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.
