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 ...

In central China's Qinglongshan fossil reserve, scientists have unearthed 28 fossilized dinosaur eggs dating back approximately 86 million years. Utilizing uranium-lead analysis on the eggshells, ...

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.

These eggs from this family might have developed special pore patterns to adapt to cooler temperatures. One batch of 28 egg-filled calcite was chosen to research, giving the ideal sample for accurate ...

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 ...
