| There is a parallel here with the hadrosaur and ceratopsian dinosaurs of the Late Cretaceous. |
|
| The associated hadrosaur material consists of four caudal vertebrae and a fragmentary dentary. |
|
| Early interpretations of fossil skin impressions suggested that hadrosaur feet were webbed. |
|
| Lambeosaurus and related genera are members of the hadrosaur subgroup, Lambeosaurinae. |
|
| Reconstruction of the hadrosaur Hypacrosaurus egg and embryo from Devil's Coulee, southern Alberta. |
|
| The large embryos almost entirely fill the eggs and the embryonic bones are sufficiently well preserved to identify the hadrosaur Hypacrosaurus. |
|
| All tyrannosaurid and hadrosaur bones lie horizontally within a 20 cm thick blocky, green claystone with occasional calcitic nodules and vertical to subvertical burrows. |
|
| The new exhibit also officially displays our hadrosaur bones, which were on loan for research and only recently returned. |
|
| The new discovery could give further insights into the hadrosaur family and aid research on diseases that afflicted dinosaur bones, which resembled those of humans, Aguilar said. |
|
| In many hadrosaur and theropod dinosaurs, the caudal vertebrae were reinforced by ossified tendons. |
|
| Most of the specimens recovered from the quarry belong to a gigantic species of hadrosaur, or duck-billed dinosaur. |
|
| The samples included the claw of a meat-eating dinosaur, a few toe bones from a ceratopsid and a duck-billed hadrosaur, and rib fragments from an unknown species. |
|
| Reports in recent years of soft dinosaur tissue from fossil bones of a T rex and a duck-billed hadrosaur elicited skepticism from the scientific community. |
|
| In the juvenile hadrosaur bone bed, after excavating for some five years, we finally found a nasal bone fragment that helped us identify the genus Gryposaurus. |
|
| Sue's close cousin, Daspletosaurus, hunches over the body of a duck-billed Hadrosaur. |
