To determine the age of a dinosaur fossil, carbon dating can never be used. By the time a dinosaur fossil was found, any carbon-14 the organism would have taken up and incorporated into its tissues during its life, would have decayed too much to be useful as a tool to determine its age.
Why cant scientists simply use the carbon left over in dinosaur bones to date their age?
Fossil bone incorporates new radiocarbon by means of recrystallization and, in some cases, bacterial activity and uranium decay. Because of this, bone mineral – fossil or otherwise – is a material that cannot yield an accurate radiocarbon date except under extraordinary circumstances.
Do dinosaurs have carbon-14?
Dinosaurs are not dated with Carbon-14, yet some researchers have claimed that there is still Carbon-14 in the bones.
How long does it take carbon to decay?
5,730 years The time it takes for 14C to radioactively decay is described by its half-life. C has a half-life of 5,730 years. In other words, after 5,730 years, only half of the original amount of 14C remains in a sample of organic material.
