Maiasaura

Maiasaura, a Hadrosaur famous as a "good mother lizard", lived in North America about 75 million years ago, probably the direct ancestor of the Hadrosaur Edmontosaurus.

In Jurassic Park
Maiasaura can be seen in both Jurassic Park novels, very docile as it would probably usually be in real life. Maiasaura did not, however, have motion-sensitive eyesight like it does in the novels.
