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.
Despite being simple test results without any interpretation, they were blocked from presentation in conference proceedings by the 2009 North American Paleontological Convention, the American Geophysical Union in 20, the Geological Society of America in 20, and by the editors of various scientific journals.

Detwiler; in 108 MA Cretaceous sandstone - identified by Dr. The "Modified Longin Method" is the normal purification method for bone collagen. Libby, the discoverer of Radiocarbon dating and Nobel Prize winner, showed that purified collagen could not give erroneous ages.
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.
Carbon-14 is considered to be a highly reliable dating technique.
It's accuracy has been verified by using C-14 to date artifacts whose age is known historically.
The amount is then compared to the initial quantity of carbon 14, and, thanks to the half-life, the age of the object is calculated.
Since 2013 KIK-IRPA uses an AMS machine of the newest generation, the so-called MICADAS (Mini carbon dating system).
The C laboratory of KIK-IRPA carries out datings for archeology, art history and geology, both for Belgian researchers and for abroad.
