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.
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.
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.
After the AOGS-AGU conference in Singapore, the abstract was removed from the conference website by two chairmen because they could not accept the findings.
Carbon-14 is considered to be a highly reliable dating technique.
But in 2014, someone told the director of the facility, Jeff Speakman, that the Paleochronology group was showing the Carbon-14 reports on a website and You Tube and drawing the obvious conclusions.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.Critics charged that the findings were mistaken or that what she called soft tissue was really biofilm produced by bacteria that had entered from outside the bone.Schweitzer answered the challenge by testing with antibodies.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.Her report in 2009 confirmed the presence of collagen and other proteins that bacteria do not make.In 2011, a Swedish team found soft tissue and biomolecules in the bones of another creature from the time of the dinosaurs, a Mosasaur, which was a giant lizard that swam in shallow ocean waters.Dinosaur bones with Carbon-14 dates in the range of 22,000 to 39,000 years before present, combined with the discovery of soft tissue in dinosaur bones, indicate that something is indeed wrong with the conventional wisdom about dinosaurs. Kline team of the Glendive Dinosaur and Fossil Museum. Triceratops #2, a very large ceratopsid-type dinosaur excavated in 2007 in Cretaceous clay at 47 02 44N and 104 32 49W in Montana by the O. Outer bone fragments of a femur were tested for C-14. Scrapings were taken from a rib still imbedded in the clay soil of a ranch in CO, partially excavated in 20, in 150 Ma (late Jurassic) strata by C. It can be as high as 20% in normal bone but decomposes over time so that there should be none after ~100,000 years.However, it has been hard to reach the public with the information. Yet it is found in four-foot long, nine-inch diameter dinosaur femur bones claimed to be greater than 65 million years old.
