Radioactive dating dinosaur bones
- At Oak Ridge National Laboratory, Scientists dated dinosaur bones using the Carbon dating method.The age they came back with was only a few thousand years old. And kept their theory that dinosaurs lived "millions of years ago" instead. They then use potassium argon, or other methods, and date the fossils again.The low activity of the carbon-14 limits age determinations to the order of 50,000 years by counting techniques." Some creationists seem to understand that rocks and minerals cannot be dated using the Carbon 14 technique.This is a quote from the CMI website and it is accurate: "Obviously this only works for things which once contained carbon—it can’t be used to date rocks and minerals, for example.Creationists bring up Carbon 14 dating of dinosaur bones all the time.
Even soft tissue has shown to be preserved with minerals such as iron rendering the method useless for dating.
Because he assumed that the earth was millions of years old, he believed it was already at equilibrium.
However each time they test it, they find more c14 in the atmosphere, and have realized that we are only 1/3 the way to equilibrium.
So a date of 9,000 or 16,000 years is more likely to be less. Carbon dating is a good dating tool for some things that we know the relative date of. Willard Libby (December 17, 1908 September 8, 1980) and his colleagues discovered the technique of radiocarbon dating in 1949.
Libbey knew that atmospheric carbon would reach equilibrium in 30,000 years.
