Libby —80 and his coworkers in — Some very unusual evidence is that living snails' shells showed that they had died 27, years ago.
The technique was developed by Willard F.

Living mollusk shells were dated at up to 2, years old. By comparing the placement of objects with the age of the rock and silt layers in which they were found, scientists could usually make a general estimate of their age. Water Balance on Earth.
Scientists have assumed that the Earth is many millions of years old, however, no one was living when the earth was formed, and no one has concrete proof as to when the Earth was formed and therefore no one can say exactly how old it is.

Take quizzes and exams. These artifacts have gone through many carbon half-lives, and the amount of carbon remaining in them is miniscule and very difficult to detect. So, we start out with two isotopes of uranium that are unstable and radioactive.
The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.
It would really be nice if geologists would just do a double blind study sometime to find out what the distributions of the ages are.
