How does radioactive dating help determine the age of fossils
The interesting part is that it is all still around, even though shuffled from here to there.
The moral of that is everything is useful in some way, known or unknown, old or new.
In particular, two important events: “In 1903, Sir Ernest Rutherford (1871-1937) along with Frederick Soddy (1877-1956) identified the phenomenon of radioactive half-life decay, and the discovery of carbon 14 in 1940 by Martin David Karmen and Sam Ruben.” An interesting new science developing, that of the new discovering the old.
This of course includes fossils, of animal and plant life.
Mostly, of course plant life would have decayed, but leaf fossils do remain if they were immediately covered by volcanic ash that preserved them from rot.
What made this discovery of Libby’s possible was the vast amount of work that had gone on before.
This can be seen along many newly built mountainous highways where various layers of rock, minerals, and vegetative materials are exposed to the human eye as the mountains have been cut through to make passageways.
Thus in fossil dating, the layer of the earth in which the fossil was found will be important in finding the age.
