More than 20 young dinosaurs died together 92 million years ago after being trapped in mud in what is now Inner Mongolia. The fossilized remains of the ostrich-like ornithomimids are rare evidence of social behavior, say scientists from Montana State University and elsewhere. No adult bones were found at the site, suggesting that the young plant-eaters traveled on their own in herds.
