New carbon dating updating social security card
He said that his team and the laboratories they employed took special care to avoid contamination.
That included protecting the samples, avoiding cracked areas in the bones, and meticulous pre-cleaning of the samples with chemicals to remove possible contaminants.
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.
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.
He is currently seeking relief in a legal action for wrongful termination and religious discrimination by California State University Northridge (CSUN).
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.
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.
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.
