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.
It's accuracy has been verified by using C-14 to date artifacts whose age is known historically.
The fluctuation of the amount of C-14 in the atmosphere over time adds a small uncertainty, but contamination by "modern carbon" such as decayed organic matter from soils poses a greater possibility for error. Thomas Seiler, a physicist from Germany, gave the presentation in Singapore.
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.
Members of the Paleochronology group presented their findings at the 2012 Western Pacific Geophysics Meeting in Singapore, August 13-17, a conference of the American Geophysical Union (AGU) and the Asia Oceania Geosciences Society (AOGS).
(4 points) Write an equation showing how (4c2c) changes with time: B.
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.
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.
