Since the very first Maiasaur discovery in Montana, a substantial amount of information has been deciphered about dinosaur nesting behaviour. They have been described as caring parents, feeding their nest bound young as well as social animals living in herds of thousands. The most important discovery of all is perhaps the change in our attitude toward dinosaurs.

" I think it's undeniable that the dinosaurs weren't just big lizards. They weren't mammals or birds, either, … They were dinosaurs, different from all living creatures in many ways, some of which we know about and some of which we'll probably never know about. The picture we have of dinosaurs will always have its blank spots, places where we have to guess to fill in an image, the way we sometimes guess when we reconstruct skeletons."
