What was life like 80 million years ago? Discover a lost world through the eyes of a very special dinosaur. MAIA is a realistic account of the life of a young dinosaur, written by the first paleontologist ever to discover an extensive dinosaur nesting ground. This discovery, made by paleontologist John R. Horner in the Montana grasslands in 1978, enabled scientists to piece together a picture of a new species of peaceable, duck-billed dinosaurs. MAIA is that story.
