Did dinosaurs return to their nest sites?

                         There is good evidence to show that dinosaurs such as the Maiasaurus migrated back to its traditional nest site every year, where it laid up to 20 eggs. Scientists have found nest sites containing masses of eggshells, together with the remains of babies of various ages, showing that the dinosaurs re-used the sites over the years.

 

How did dinosaurs look after their young?

                         Originally it was thought that dinosaurs laid their eggs in isolated places, but in 1978 a remarkable find was made in Montana, USA. Fifteen Maiasaurus babies were found scattered around a large mound-shaped structure, together with many broken eggshells. The babies were not newly hatched because their teeth were partly worn. The nest was about 2 m across, and covered with vegetation. In the Gobi desert, the pig-sized dinosaur Protoceratops dug holes in the sand and buried her eggs. She left them to hatch in the heat of the sand while she guarded them from predators.
