Radioactive dating dinosaur bones
Critics charged that the findings were mistaken or that what she called soft tissue was really biofilm produced by bacteria that had entered from outside the bone.
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.
Carbon dating at this facility is certainly the very best.
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 You Tube and drawing the obvious conclusions.
Carbon dating is one type of radiometric dating, there are others.
Carbon dating uses the carbon-14 isotope, with a half life of about 5700 years. If so, the official definition is "the determination of the age or date of organic matter from the relative proportions of the carbon isotopes carbon-12 and carbon-14 that it contains". Carbon dating is the radio-activity of Carbon 14 which is unstable so it emits protons once in a while in order to become a more stable isotope.
