­ ­You probably have seen or read news stories about fascinating ancient artifacts.

At an ar­chaeological dig, a piece of wooden tool is unearthed and the archaeologist finds it to be 5,000 years old.

"We didn't tell them that the bones they were dating were dinosaur bones. The Allosaurus dinosaur was supposed to be around 140,000,000 years.

The samples of bone were blind samples.""Of course carbon dating isn't going to work on your Allosaurus bone. So I would expect to get some weird number like 16,000 years if you carbon date a millions of years old fossil.

What methods do they use and how do these methods work?
