Researchers in China achieved a milestone by directly dating a fossilized dinosaur egg at 85.9 million years old, marking a first in paleontology. Using carbonate uranium-lead (U-Pb) dating, ...

For the first time, scientists have dated dinosaur eggs that lay buried in rock for millions of years, using a groundbreaking new ‘atomic clock for fossils’ method. During the Cretaceous period, Earth ...

Researchers collected and vaporized samples from fossilized eggshells in China's Qinglongshan fossil reserve. They calculated how old the eggs were by measuring accumulated lead and uranium atoms in ...

Using uranium-lead dating, researchers calculated the age of the eggs, rather than the sediments around them, at the Qinglongshan site in China ...

A remarkably well-preserved dinosaur embryo, unearthed from a fossilized egg in southern China, is offering scientists an ...

The story of that discovery begins just over 100 years ago, when swashbuckling fossil hunter Roy Chapman Andrews first dug up a clutch of dinosaur eggs in intact nests in Mongolia. (Although hailed as ...
