For example, it makes it possible to compare the ages of objects on a worldwide scale, allowing for indispensible comparisons across the globe.
Before this, it was anyone's guess how different digs' timelines compared to one another over great distances.
For the most part, radiocarbon dating has made a huge difference for archaeologists everywhere, but the process does have a few flaws.
For example, if an object touches some organic material (like, say, your hand), it can test younger than it really is.
Also, the larger the sample the better, although new techniques mean smaller samples can sometimes be tested more effectively.
