Should baby dinosaurs be taken good care of by mother?

Started from 1980s, amazing discoveries were found in succession. People discovered numerous dinosaur nests, the width of each nest was about 2 meters and the depth was about 1 meter.

People also found a nest with over 10 baby hadrosaurs. They are about 30 to 35 centimeters long after they hatched from 20-centimeter eggs. Baby hadrosaurs may stay in nest for a long time, be taken good care of and fed by their mother. So hadrosaurs also called maiasaura. The weight of hadrosaurs may under 2 tons because they can hatch. Maybe the nest made of plant could provide enough heat for hatch by fermentation.

At the same time, there were other dinosaurs’ nests beside, with 24 oblong dinosaur eggs in it. This kind of baby dinosaur went out in groups instead of staying in nest.

So we make sure that there were two different growing styles of dinosaur. The baby dinosaurs which were taken good care of by their mothers grew fast. In contrast, other dinosaurs lived an independent life after they being hatched.
