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.

It serves as the dinosaur antagonist in the prologue and the film itself. Trevorrow saved the Giganotosaurus for the third Jurassic World film to set up a rivalry between it and the T. rex. In the prologue, a Giganotosaurus kills a T. rex in battle during the Cretaceous, and two cloned versions face off in the subsequent film, set during the ...
The size of the two Saurolophus species compared to humans Saurolophus is known from material including nearly complete skeletons, giving researchers a clear picture of its bony anatomy. S. osborni , the rarer Albertan species, was around 8.2–8.5 m (27–28 ft) long, with its skull 1.0 m (3.3 ft) long.

In the first episode the survival strategies of the late-Cretaceous sauropod Sauroposeidon are contrasted with those of Tyrannosaurus rex.The primary distinction drawn is the difference between Sauroposeidon's speculated r selector method of reproduction (i.e. many offspring with no parental care) versus T. rex's proposed K selector method (i.e. few offspring with very invested parental ...
Parasaurolophus, a crested hadrosaur.. Hadrosaurids, also commonly referred to as duck-billed dinosaurs or hadrosaurs, were large terrestrial herbivores.The diet of hadrosaurid dinosaurs remains a subject of debate among paleontologists, especially regarding whether hadrosaurids were grazers who fed on vegetation close to the ground, or browsers who ate higher-growing leaves and twigs.

Sexual dimorphism in dinosaurs refers to the different physical characteristics of male and female dinosaurs of the same species. This means that the male and female dinosaurs of a species may differ in size, color, shape, or they may even look like a completely different species altogether, such as in the case of the anglerfish.
