In a stratigraphical context objects closer to the surface are more recent in time relative to items deeper in the ground.
This means that we cannot figure out the age of dinosaur fossils, or any ancient mammals and reptiles.
Another one of its flaws is that it is not extremely accurate.
Libby estimated that the steady state radioactivity concentration of exchangeable carbon 14 would be about 14 disintegrations per minute (dpm) per gram.
In 1960, Libby was awarded the Nobel Prize in Chemistry for this work.
Radiocarbon dating, or simply carbon dating, is a technique that uses the decay of carbon 14 to estimate the age of organic materials.
