Parasaurolophus (/ ˌ p ær ə s ɔː ˈ r ɒ l ə f ə s,-ˌ s ɔːr ə ˈ l oʊ f ə s /; meaning "beside crested lizard" in reference to Saurolophus) [2] is a genus of hadrosaurid "duck-billed" dinosaur that lived in what is now western North America and possibly Asia during the Late Cretaceous period, about 76.9–73.5 million years ago. [3]
Spondyloarthropathy has been documented in the spine of a 78-million year old hadrosaurid. [ citation needed ] Other examples of pathologies in hadrosaurs include healed wounds from predators, such as those found in Edmontosaurus annectens , and tumors such as Langerhans cell histiocytosis, hemangiomas, desmoplastic fibroma, metastatic cancer ...
A herd of Alamosaurus search the plains of Mexico for food. A female lays a clutch of eggs as a large asteroid hits nearby, sending debris into the air. The explosion heats the air to hundreds of degrees as burning debris rains down. A magnitude 11 earthquake and blast wave finishes off the last of the Alamosaurus
Paleontologists found 100 eggs and 80 skeletons from a dinosaur called Mussaurus at a site in Patagonia, suggesting the animals lived in groups.
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. [1] However, the most reliable early record of North American dinosaurs comes from fragmentary saurischian fossils unearthed from the Upper Triassic Dockum Group ...
Brown wasted little time in describing his material, [1] [2] giving it its own subfamily. [3] Saurolophus was an important early reference for other hadrosaurs, as seen in the names of Prosaurolophus ("before Saurolophus") and Parasaurolophus ("near Saurolophus"). However, little additional material has been recovered and described.

Lambeosaurines originated on the continent of Laurasia during the Late Cretaceous, being initially found throughout modern Europe and Asia.Around the Campanian stage, lambeosaurines of the tribe Corythosauria colonized the landmass of Laramidia (modern western North America) via Beringia and spread as far south as Mexico, radiating into a diverse array of a body plans, including famous taxa ...
