Maiasaura, a hadrosaurid genus, famous as a "good mother lizard," as fossils show it cared for its young. Maiasaura also were light weight for their size and could run. It lived in North America about 75 million years ago, probably the direct ancestor of the Hadrosaur Edmontosaurus. It was named by Jack Horner and Robert Makela in 1979.


Astronaut Loren Acton took a bone fragment and eggshell piece of a Maiasaura on an 8-day Spacelab 2 mission in 1985—the first dinosaur in space.[1]

Maiasaura had a small but pointed crest on the top of its head, and may have been used to headbutt with competition or to attract mates. Like most hadrosaurs, they were able to walk on two legs and four legs at the same time. Its only weapon against predators is its muscular tail and herds.

Story

During the Isla Sorna Incident (1997) a info sheet of Maiasaura can be seen, anyways, no other information about this species is disclosed either in the InGen list or by the DPG, so the state of possible activity of the species on any island is unknown.

Maiasaura do not appear physically in any of the 5 Jurassic Park films so far, though it was mentioned in scene 33 of the script for the second film, and some of their behavioural characteristics were transferred to the Parasaurolophus.
