Augustynolophus

Augustynolophus is an extinct genus of herbivorous saurolophine hadrosaur dinosaur which was discovered in the Moreno Formation in California, dating to the late Maastrichtian age, making it one of the last non-avian dinosaurs known from the fossil record before the Cretaceous–Paleogene extinction event.

==History of discovery== thumb|left|Pectoral and limb elements The generic name derives from a combination of the Augustyn family, who helped support the Los Angeles County Museum, and the suffix "-lophus," meaning crest, a reference to its relative Saurolophus. The specific name refers to palaeontologist William Morris. It was originally described as a species of Saurolophus, S. morrisi. However, when a more in-depth study took place, the end results revealed that its cranial structure was vastly different when it was juxtaposed with the other known members of the tribe Saurolophini, most notably Saurolophus osborni and Saurolophus angustirostris and Prosaurolophus maximus and therefore, it was determined to be a separate genus.
