Unfortunately, these elements don't exist in dinosaur fossils themselves. This effect is accounted for during calibration by using a different marine calibration curve; without this curve, modern marine life would appear to be years old when radiocarbon dated. For accelerator mass spectrometrysolid graphite targets are the most common, although gaseous CO 2 can also be used. China hosts 20 million years old. Radiocarbon dating prove the same age of years. Libby's method was soon superseded by gas proportional counterswhich were less affected by bomb carbon the additional 14 C created by nuclear weapons testing.
Radio carbon dating can be used to find the age of dinosaur fossils
Rachel. generaly i keep healthy style of life- my mind is always positive, i dont drink any alcohol, i enjoy eating quality meal, i practise thai chi, tenis. i am reading books and love nature and animals. i am not kind of party person. if you have the same life style, we may have a quality moments together. i like nice and intelligent conversation about anything. i am very strick about the hygiene....

How Do Scientists Determine the Age of Dinosaur Bones?
In fact, if the entire earth were solid carbon, in a million years so much would have decayed that there would not be even a single atom of carbon left. Method of chronological dating using radioactive carbon isotopes. Overall, the mixing of deep and surface waters takes far longer than the mixing of atmospheric CO 2 with the surface waters, and as a result water from some deep ocean areas has an apparent radiocarbon age of several thousand years.
