Parasaurolophus
Parasaurolophus is a medium sized herbivore and currently one of three ornithopods in the game, joined by the small Oryctodromeus and the semi-aquatic Lurdusaurus.
As a hadrosaur, the Parasaurolophus lacks the major offensive capabilities of the other herbivores currently in the game. While it could be just as dangerous as other dinosaurs, if given the chance, Parasaurolophus' primary defense is to flee from large threats such as Acrocanthosaurus or Megalosaurus. It uses its superior speed and stamina to outlast them in a chase. Even if caught, a Parasaurolophus can take a number of hits before going down, allowing it to fight back against its assailants or possibly escape before death by tiring them out.
Unique Ability: The Parasaurolophus is able to lock on to enemies, emitting a sophisticated alarm call as well as highlighting the enemy for all members of its group. The call varies depending on the severity of the threat, with a total of 3 tiers (Minor, Moderate, and Major threat).
Other Facts: Parasaurolophus falls prey to many species of carnivores, but a healthy adult is no pushover. Powerful legs and a considerable weight allow adults to severely injure, and possibly even kill, smaller carnivores that they cannot outrun.
The Parasaurolophus has a characteristic crest which it uses to communicate with herd members.
The Parasaurolophus is able to graze while moving at the same time, and is the only herbivore in the game that can do so.
