Researchers have found that fossilized dinosaur eggshells contain a natural clock that can reveal when dinosaurs lived. The technique delivers surprisingly precise ages and could revolutionize how ...

Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years. Mountains have been built and eroded, continents and oceans have moved ...

These radioactive elements decay at known rates, effectively acting as a built-in clock that reveals precisely when the eggs were buried millions of years ago. This natural timekeeping mechanism has ...

New research shows that fossilized dinosaur eggshells can be used to help scientists more precisely date prehistoric nesting ...

Fossils are invaluable archives of the past. They preserve details about living things from a few thousand to hundreds of millions of years ago. Studying fossils can help us understand the evolution ...
