Carbon dating used date specimens Chatcamfree espana
That included protecting the samples, avoiding cracked areas in the bones, and meticulous pre-cleaning of the samples with chemicals to remove possible contaminants.Knowing that small concentrations of collagen can attract contamination, they compared precision Accelerator Mass Spectrometry (AMS) tests of collagen and bioapatite (hard carbonate bone mineral) with conventional counting methods of large bone fragments from the same dinosaurs. Mary Schweitzer, associate professor of marine, earth, and atmospheric sciences at North Carolina State University, surprised scientists in 2005 when she reported finding soft tissue in dinosaur bones.
Radiocarbon dating is used to date very recent artifacts, and is usually useful only for archeological purposes.
carbon 14 ----------------------------------- No, NOT Carbon 14, Carbon 14 dating CAN ONLY BE USED is living (or once living) things.
The Atoms used for radiometric dating of NON LIVING things are: Potassium/Argon Uranium/Lead Scientists use carbon dating as well as: Various radioisotope dating methods (note: carbon-14 dating does not work on fossils as they are generally too old for any carbon-14 to remain). Carbon dating is mainly used by archaeologists to date recent finds as the technique is only accurate for 50,000 to 60,000 years in the past.
Carbon 14 is used, mainly by archaeologists, to date bones and other formerly living matter but not normally fossils.
This is because the half-life of that isotope is 5730 years; it is useful for dating up to 50,000 - 60,000 years but no more.
