Orodromeus

Order: Ornithischia · Suborder: Ornithopoda · Family: Hypsilophodontidae
Orodromeus eggs, embryos, and babies were discovered in Montana. These rare finds provide insight into the way in which dinosaurs laid their eggs and cared for them, as well as how the embryos developed and were nutured after they hatched. Like Maiasaura young, Orodromeus hatchlings were cared for by their parents until they were old enough to fend for themselves.
