Stuck-osaurus: Mass grave unearthed of young dinosaurs who died 90million years ago after getting trapped in the mud

Wednesday, May 25, 2011

Scientists have unearthed a mass grave of young dinosaurs that became trapped in mud 90 million years ago.

Fossilised skeletons of more than 25 of the bird-like animals were discovered at one site in northern China's Gobi Desert.

The creatures appear to have strayed into the boggy margins of a lake and perished as they struggled to escape.

Evidence suggests their legs were stuck deep into the mud, and one individual had tumbled on top of another.

The discovery sheds light on dinosaur social behaviour, indicating that juvenile individuals were left to fend for themselves when adults were preoccupied with nesting or brooding.
