Dinosaurs may have been doting parents
A fossil of one adult Psittacosaurus dinosaur surrounded by 34 juveniles has provided the most compelling evidence to date that dinosaurs raised their young after hatching. Previously discovered fossils of teeth found at the same site in China from Allosaurus dinosaurs of differing ages, and fossils of groups of young Maiasaura have hinted that dinosaurs may have indulged in parental care. But what makes this 125-million-year old fossil find from Liaoning province more convincing is that the skeletons are complete, and crowded together in life-like positions with their legs tucked under and heads raised, indicating that they were buried alive rather than swept together after death.
