Africa roughly two million years ago. Scientists have unearthed various P. robustus fossils, but because of the specimens’ age, they haven’t been able to glean much from them.Now, using a novel method ...

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

At a site known as Natural Trap Cave, a team of scientists are rappelling down to uncover the secrets of what the Earth was ...

Two fossils of singing cicadas, one of which was remarkably well preserved, reveals that the insects dispersed in Europe millions of years earlier than once thought.

Its newly described relative is the earliest singing cicada ... the Messel Pit in Germany, a rich fossil site dating to the Eocene epoch (57 million to 36 million years ago).

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 ...

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 ...

Dating fossils relies on several scientific methods, adapted to the age and context of the discoveries. For fossils as old as Pink's, researchers primarily use relative and absolute dating techniques.

In the mid-1990s, scientists identified an early human relative known as ... did not directly date the fossils but, based on three different ways of dating the layer of sediment in which the ...
