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 ...

New fossil egg discoveries show early dinosaurs and marine reptiles laid soft-shell eggs like those of turtles, snakes and lizards and not the hard shells of bird eggs today, according to a new study.

Scientists directly dated dinosaur eggshells in China, finding them 85.91 million years old, revolutionizing fossil timelines.

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

Paleontologists working in central India have made a rare discovery — a fossilized dinosaur hatchery with 92 nests and 256 eggs belonging to colonies of giant plant-eating titanosaurs. A study of the ...

A treasure trove of fossil nests uncovered in India hints at an array of as-yet-undiscovered dinosaurs belonging to the titanosaur group, and gives clues to how these animals reproduced. A total of 92 ...

Interestingly, the laser-based method led to successfully dating a cluster of dinosaur eggs from the Qinglongshan site, central China, to 85 million years ago (Late Cretaceous period). The fossilised ...

(A) A completely unhatched egg. (B) An almost fully intact circular outline of an egg. (C) A compressed egg showing a hatching window. (D) An egg showing a curved outline. (E) A deformed egg showing ...

Dinosaur eggs laid 85 million years ago have been accurately dated using a new "atomic clock for fossils" method. The eggs could improve understanding of Earth's climate when dinosaurs roamed the ...
