Some paleontologists think the fact that fossilized hadrosaur babies and adolescents were found in nests proves that hadrosaurs guarded their young in nests long after the young were hatched from eggs. The author points out that similar nests for young crocodiles are made by modern crocodiles, even though crocodiles do not guard their young for a long time after hatching.
The discovery of fossilized hadrosaur babies and adolescents in their nests does not prove that hadrosaurs guarded their young in nests long after the young were hatched from eggs.
