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.
Schweitzer herself wonders why these materials are preserved when all the models say they should be degraded.
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.
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.
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.
