An international team of geologists and paleontologists is pioneering a groundbreaking methodology to reliably determine the age of fossil-bearing rocks—by directly dating fossilized dinosaur ...

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 ...

Layers of rock can tell the story of life on Earth, but only if you know when each chapter was written. For many dinosaur sites, that date has been little more than a rough guess. Now, a team of ...

When paleontologists dig up a fossil from the ground, how do they figure out the age of the piece of history? It’s not as simple as you may think. To discover more about jaw-dropping finds–like the ...

Fossils can reveal traces of an ancient world, but their exact age is not always easy to discern. Palaeontologists have traditionally relied on a range of methods to date fossil sites, some more ...

A trove of specimens from New Mexico may help settle a long-running argument about the diversity of dinosaurs before their extinction. A life reconstruction of Alamosaurus sanjuanensis, from the ...

Artistic reconstruction of a newly hatched troodontid-like dinosaur resting among fragments of its eggshell (loosely based on Mongolian microtroodontid-type). These eggshells, when buried within ...
