Maiasaura

Maiasaura, a Hadrosaurid genus, famous as a "good mother lizard," 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!
