Dinosaur fossils are too old to be reliably dated using carbon-14, which has a half-life of about 5730 years. Suppose we had a 69 million year old dinosaur fossil. How much of the living dinosaur's 14C would be remaining today? (Round your answer to five decimal places.)

Carbon-14 Dating Dinosaur Bones

Explanation:

The half-existence of carbon-14 is just 5,730 years, so carbon-14 dating is just effective on samples that are under 50,000 years of age Dinosaur bones are a great many years old a few fossils are billions of years old These incorporate radiometric dating of volcanic layers above or below the fossils or by correlations with comparable rocks and fossils of known ages Radiocarbon dating includes deciding the age of an old fossil by measuring its carbon-14 substanceCarbon-14, or radiocarbon, is a normally happening radioactive isotope that structures when cosmic rays in the upper environment strike nitrogen particles, which at that point oxidize to become carbon dioxide
