Beyond the game
The real Maiasaura
Nests and young found in Montana changed ideas about dinosaur behavior. The finds suggest that adults cared for their young while they stayed in the nest.
Its fossils appeared along with numerous nests at the Egg Mountain site, Montana. The attention to the young is interpreted from the set of findings. It is an explanation supported by fossils, although it does not allow us to observe all the care that an adult provided.
Hadrosaurids had dental batteries for processing vegetation. Some had hollow crests and others lacked them: “duck-billed” does not mean they were ducks or that they all ate the same foods.
