Note: only the third of those four necessary facts can be measured, the other three must be estimated, assumed, or extrapolated. During each half-life (~5,730 years), about half of the remaining C14 atoms in a specimen are expected to decay.
Since dinosaurs are thought to be over 65 million years old, the news is stunning - and more than some can tolerate.
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 (C-14) dating of multiple samples of bone from 8 dinosaurs found in Texas, Alaska, Colorado, and Montana revealed that they are only 22,000 to 39,000 years old.
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).
Libby, the discoverer of the C14 dating method, was very disappointed with this problem.
He understood that archaeological artifacts were readily available.
One doesn't exclude the other, but watch, all of the Christians who have never studied evolution and merely taken their pastor's word will give me a thumbs down.
—Charles Ginenthal, 1997 Many of the most obvious conflicts between science and religion involve timing issues—the dating of events in Earth’s history. Scott wrote: “It has long been acknowledged, though not always fully acted upon, that radiocarbon dating measurements are not definitive, i.e. “If a C14 date supports our theories, we put it in the main text.
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.
