Maiasaura

Maiasaura, duck-billeddinosaurs(hadrosaurs) found as fossils from the LateCretaceous Period(about 100 million to 65.5 million years old) ofNorth Americaand whose discovery led to the theory that these bipedal herbivores cared for their young.

In 1978 aMaiasauranesting site was discovered in the Two Medicine Formation near Choteau,Montana, U.S. The remains of an adultMaiasaurawere found in close association with a nest ofjuveniledinosaurs, each about 3.3 feet long. Hatchlings that were too large to fit into eggs, and nests with clutches of eggs, as well as many broken eggshells, were found nearby. The bones of the embryos, however, were not fully ossified, which means the young could not have walked immediately upon hatching and would have required some degree of parental care. Hundreds of skeletons preserved in one specific ashbed in Montana, as well as those preserved in nesting sites, suggest thatMaiasaurawas migratory. Such evidence also demonstrates that these dinosaurs were social animals that nested in groups; they probably returned to the same nesting site year after year. Studies of bone structure indicate that it would have taken about seven or eight years forMaiasaurato reach an adult size.
