Question: Why cant carbon 14 dating BE USED FOR AGES 50 000 years and older?

Carbon dating also cannot be used on artifacts over about 50,000 years old. These artifacts have gone through many carbon-14 half-lives and the amount of carbon-14 remaining in them is miniscule and very difficult to detect.

Why cant geologist use the carbon-14 method to date igneous rocks Why cant they use the carbon-14 method to date dinosaur bones?

But carbon-14 dating wont work on dinosaur bones. The half-life of carbon-14 is only 5,730 years, so carbon-14 dating is only effective on samples that are less than 50,000 years old. To determine the ages of these specimens, scientists need an isotope with a very long half-life.

What are 2 limits of using carbon-14 in dating the age of objects?

First, the older the object, the less carbon-14 there is to measure. Radiocarbon dating is therefore limited to objects that are younger than 50,000 to 60,000 years or so.
