14 carbon dating
From 2007 through 2011 the Paleochronology group had 11 dinosaur bone samples carbon dated by the Center for Applied Isotope Studies at the University of Georgia, and for good reason.
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.
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.
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.
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.
