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]
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. Instead, more abundant remains from Asia have provided more data.
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 ...
Lambeosaurini is defined as all taxa more closely related Lambeosaurus lambei than to Parasaurolophus walkeri, and Parasaurolophini as all those taxa closer to P. walkeri than to L. lambei. In recent years Tsintaosaurini and Aralosaurini have also emerged.
Prosaurolophus (/ ˌ p r oʊ s ɔː ˈ r ɒ l ə f ə s /; meaning "before Saurolophus", in comparison to the later dinosaur with a similar head crest) is a genus of hadrosaurid (or duck-billed) dinosaur from the Late Cretaceous of North America. It is known from the remains of at least 25 individuals belonging to two species, including skulls ...

Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
