In relative dating, scientists compare fossils with other objects, such as rocks, found at a particular site. Using these methods, scientists have found that dinosaurs roamed the Earth from ...

How do we know when they lived? Estimating the age of hominid fossils is usually a painstaking, two-part process, involving both "absolute" and "relative" dating. "Absolute" dating means finding a ...

A cutting-edge technique for analyzing fossil tooth enamel is revealing remarkable new information about 2 million-year-old ...

To do this, they compare how high or low a fossil site is relative to that boundary. However, this method only gives a rough age estimate rather than a precise date, unlike absolute dating methods ...

Scientists have discovered a trove of rare dinosaur bones dating back 115 million ... an early T. rex relative — and the second-oldest stingray fossil ever found on Earth. The fossils will ...

The reason for two sets of fairly divergent age ranges has to do with the methods used to date the fossil. Because of the jawbone’s degradation, the team couldn’t use direct dating techniques ...

Over time, it breaks down into something else. Scientists analyzed the Siberian unicorn fossils with carbon dating. This uses a radioactive isotope of carbon called carbon-14. “Over 5,730 years ...

How do we know when they lived? Estimating the age of hominid fossils is usually a painstaking, two-part process, involving both "absolute" and "relative" dating. "Absolute" dating means finding a ...
