Can radiocarbon dating be used to determine the age of dinosaur fossils explain
Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and from that point onwards the amount of 14 C it contains begins to decrease as the 14 C undergoes radioactive decay. Measuring the amount of 14 C in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.

Fossils are the remains of animals or plants that lived a long time ago. When we think of fossils, the first things that come to mind are the bones of dinosaurs; but a fossil can be anything. Footprints, flowers, even droppings; all of these things can be turned into fossils under the right conditions. A fossil only becomes a fossil when it has reached a certain age. Though there is no one age, a good rule is anything over 10, years old can be considered a fossil. The oldest fossils ever discovered are more than 3. Fossils are found all over the world and on every continent.
How Do Scientists Date Ancient Things?
The most widely known form of radiometric dating is carbon dating. This is what archaeologists use to determine the age of human-made artifacts. But carbon dating won't work on dinosaur bones.
