Maiasaura is a characteristic fossil of the middle portion (lithofacies 4) of the Two Medicine Formation, dated from about 86.3 to 70.6 million years ago. [2] Maiasaura lived alongside the troodontids Stenonychosaurus and Troodon and the basal ornithopod Orodromeus, as well as the dromaeosaurid Bambiraptor and the tyrannosaur Daspletosaurus. [2]

When the eggs hatch, one is a male Maiasaura, whom the mother names Light, and the other is a Tyrannosaurus, named Heart.

That same year, Case and others reported the discovery of hadrosaur bones in Vega Island, Antarctica. After decades of such ...
The earliest potential record of dinosaurs in North America comes from rare, unidentified (possibly theropod) footprints in the Middle-Late Triassic Pekin Formation of North Carolina.

Stegoceras is a genus of pachycephalosaurid (dome-headed) dinosaur that lived in what is now North America during the Late Cretaceous period, about 77.5 to 74 million years ago (mya). The first specimens from Alberta , Canada, were described in 1902, and the type species Stegoceras validum was based on these remains.
