Pterosaur eggs unearthed in China

Chinese researchers have announced the rare discovery of fossilised pterosaur eggs.

Xiaolin Wang from the Chinese Academy of Sciences and colleagues uncovered five three-dimensionally preserved pterosaur eggs at a site in China’s Xinjiang province. Prior to this find only four pterosaur eggs – all flattened – had ever been discovered.

The eggs are thought to be about 120 million years old and were unearthed alongside at least 40 pterosaur skeletons, suggesting that the species (newly described as Hamipterus tianshanensis) lived in flocks.
