1

Maiasaura means 'good mother lizard' because fossils show adults cared for their young.12

2

A huge nesting site was found in Montana in 1978, with nests, eggs, and baby skeletons.2

3

Baby Maiasaura were too big to fit inside eggs when they hatched, and their bones were not fully hardened.2

4

Hatchlings were about 0.5 metres (1.6 feet) long, while juveniles reached about 1 metre (3.3 feet).2

5

Hundreds of Maiasaura skeletons were found together in one ash bed, suggesting they lived in herds.2

6

Maiasaura could walk on two legs or all fours.1
