Every dinosaur was once a baby, but each species had a slightly different path to adulthood. Maiasaura dinosaurs stayed in mud nests as hatchlings. Argentinosaurus dinosaurs were on their own when they were newly hatched, because they were so small that their herd would have trampled them. It's hard to believe that the tiny Argentinosaurus babies grew up to be some of the biggest creatures that ever lived. Further information about the dinosaurs featured in the book. Glossary.
