Carbon dating fabric
If the fossil has 35% of its carbon 14 still, then we can substitute values into our equation.So, the fossil is 8,680 years old, meaning the living organism died 8,680 years ago.
Some examples of the types of material that radiocarbon can determine the ages of are wood, charcoal, marine and freshwater shell, bone and antler, and peat and organic-bearing sediments.
For example, say a fossil is found that has 35% carbon 14 compared to the living sample. We can use a formula for carbon 14 dating to find the answer.
