My Notes Ask Your e. O 22 points 1 Previous Answers SBioCaic1 3.6.012 Dinosaur fossils are often dated by using an element other than carbon, like potassium-40, that has a longer half life (in this case, approximately 1.25 billion years). Suppose the minimum detectable amount is 0.1% and a dinosaur is dated with 40K to be 68 million years old. Is this possible? O Yes, it is possible to date this fossil with 40K. O No, it is not possible to date this fossil with 40k. What is the maximum age of a fossil that we could date using 40K?

Explanation / Answer

From the question we see that the maximum age of a fossil that could date using 40K is 12.5 billion years.

67 million years is less than 12.5 billion years..

So it is possible to date this fossil with 40K

and  

The maximum age of a fossil that could date using 40K is 12.5 billion years. (It remains the same as the question on board )
