It’s hard to imagine that fierce dinosaurs once emerged from small, fragile eggs. And it may be even harder to imagine that some of those eggs, when fossilized, could have been preserved for tens of ...

A group of Chinese researchers has accomplished a remarkable feat. Using a new method, called in-situ carbonate uranium-lead (U-Pb) dating, a team of researchers has now been able to determine the ...

A clutch of 28 dinosaur eggs found in the Qinglongshan fossil reserve in central China is about 86 million years old, according to scientists who used an “atomic clock” method to date the samples.

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 ...

Thirty years ago, thousands of fossilized dinosaur eggs were discovered in Yunyang District in central China. Now, for the first time, researchers have directly dated the preserved shells, using a ...

Dating dinosaur eggs has always been tricky because traditional methods rely on surrounding rocks or minerals that may have shifted over time. Now, for the first time, scientists have directly dated ...

Crystals hidden inside dinosaur eggs at a famous fossil site are giving scientists a chance to do something that’s long proven elusive: figure out how old the ancient nests really are. Finding these ...

Laser method could help to pinpoint the age of many fossils, but some palaeontologists say further research is needed to verify the technique. Scientists in China have calculated the direct age of a ...

In the Cretaceous period, Earth was plagued by widespread volcanic activity, oceanic oxygen depletion events, and mass extinctions. Fossils from that era remain and continue to give scientists clues ...
