Maiasaura means “good mother reptile.”Most
dinosaurs laid their eggs on open ground and then left
them to hatch on their own. But the mother Maiasaura
laid her eggs in a nest, stayed close to the nest until
the eggs hatched, and then kept watch over her babies
until they were strong enough to fend for themselves.
