Radiocarbon dating is one such type of radiometric dating.

A process for determining the age of an object by measuring the amount of a given radioactive material it contains.

Half of 50% is 25%, so you would have 25% Carbon-14 and 75% Nitrogen-14.

This is what your readout said, so your fossil has undergone two half-lives.

The fossil record may be incomplete and may never fully completed, but there are still many clues to evolution and how it happens within the fossil record.

One way that helps scientists place fossils into the correct era on the Geologic Time Scale is by using radiometric dating.

As radioactive isotopes of elements decay, they lose their radioactivity and become a brand new element known as a daughter isotope.At one half-life, you would have approximately 50% Carbon-14 and 50% Nitrogen-14.In other words, half (50%) of the Carbon-14 you started with has decayed into the daughter isotope Nitrogen-14.In relative dating the exact age of the object is not known; the only thing which made clear using this is that which of the two artifacts is older.
