The bone was 68 million years old, and conventional wisdom about fossilization is that all soft tissue, from blood to brains, decomposes. The half-life of the isotope being measured determines how useful it is at dating very old samples. The short half-life is only part of the problem when dating dinosaur bones — researchers also have to find enough of the parent and daughter atoms to measure. The most widely known form of radiometric dating dinosaur brains is carbon dating.

The half-life of carbon is only 5, years, so carbon dating is only effective on samples that are less than 50, years old. Dinosaur bones, on the other hand, are millions of years old — some fossils are billions of years old.

Using the basic ideas of bracketing and radiometric dating, researchers have determined the age of rock layers all over the world.
