But in 2014, someone told the director of the facility, Jeff Speakman, that the Paleochronology group was showing the Carbon-14 reports on a website and YouTube and drawing the obvious conclusions. How long could the organisms keep on living after they were cut off from everything except the finite nutrients in the dinosaur? Bone from the Klondike District, Yukon Territory, Canada.

Most papers are not accepted, because there is a limit to the number of slots available. Thus a sample that dates to 40,000 years by C14 dating still has about 7 billion C14 atoms per mole of carbon. The half-life of the isotope being measured determines how useful it is at dating very old samples.

How Do Scientists Determine the Age of Dinosaur Bones? - The results varied widely though consistently with a normal distribution of errors in the measurements , and included multiple date ranges of 1σ confidence that did not overlap with each other.

New science directly challenges the millions-of-years dogma scattered throughout the blockbuster movie Jurassic World. The last article in the issue presents never-before-seen carbon dates for 14 different fossils, a dinosaurs. Because radiocarbon decays relatively quickly, fossils that are even 100,000 years old should have virtually no radiocarbon left in them. In the movie, fictional scientists essentially resurrect and genetically redesign dinosaurs, pterosaurs, and even a giant mosasaur—creatures supposedly extinct for 65-75 million years. Five different commercial and academic laboratories detected carbon-14 in all the samples, whether from Cenozoic, Mesozoic, or Paleozoic source rocks. How did that radiocarbon get there? The team also compared the results to several dozen published carbon-14 results for fossils, wood, and coal from all over the world and throughout the geologic column. Comparable amounts of radiocarbon showed up in almost 50 total samples. This has been argued before, but the testing process itself is loaded with procedures that rigorously remove contaminants. Broad-brushed claims of contamination weaken with every new documented carbon date from really old material. Jurassic World delivers good entertainment as long as viewers overlook its bad science.
