Highway sign at Egg Mountain in Montana. At Egg Mountain, nests and eggs of the duck-billed dinosaur, Maiasaura peeblesorum, (Montana State Fossil) and the small plant-eater Orodromeus makelai have been found. The 1978 discovery of fourteen dinosaur nests by Jack Horner helped convince other paleontologists that dinosaurs built vast colonies in order to better care for their young in a manner similar to birds. It is now widely believed that all dinosaurs reproduced by laying eggs.
