Dinosaur

Dinosaurs are the environment modifiers of Jurassic Marsh. They are invulnerable creatures which appear on their own as the level progresses, and will be triggered upon meeting zombies which they find nuisances, unleashing special abilities that will usually aid the horde. They can be turned against their former allies with the use of the Perfume-shroom, which will cause the dinosaurs to attack the zombies using a separate set of attacks. Regardless of whether the dinosaurs are charmed or not, they will leave the field after a while.

Trivia

 * Among the reptiles shown in Jurassic Marsh, the pterodactyls (being a genus of Pterosaurs) are the only ones that are not scientifically classified as dinosaurs.
 * A charmed pterodactyl will only drop the head, arm, and armor of the zombie it abducts.
 * Any zombies that are dropped by pterodactyl after all other zombies are killed will also die like Prospector Zombie, Zombie King, and Fisherman Zombie.
 * Raptors' kicks and stegosaurus' hits can be affected by Blover if it is used with fast skills.
 * Pterodactyl and its carried zombie are not affected by Blover.
 * Zombies that are in the stegosaurus' tail or carried by pterodactyls are immune to damage, with the exception of instant kills.
 * Raptors can trample the flowers without making the player fail.
 * These are the only environment modifiers that are living creatures.
 * Dinosaurs do not interact with zombies hypnotized by Hypno-shroom.
 * Raptors and pterodactyls can miss zombies when they kick them or grab them respectively, either when the zombie dies early or is blown backwards.
 * A charmed raptor can sometimes glitch out, turning around to the left after kicking a zombie. If this happens, it will not kick any more zombies, becoming useless; nonetheless, the threat they posed was neutralized.
 * Despite the world being named Jurassic Marsh, stegosaurus is the only dinosaur that existed during the Jurassic period, along with the pterodactyls (pterosaurs). The other dinosaurs existed in the Cretaceous period.
 * Ankylosaurus is the only dinosaur that can affect plants as well as zombies.
 * Ankylosaurus walks and holds its tail over its head like a scorpion.
 * T-rex and pterodactyl are the only dinosaurs that do not throw or push the zombies forward.
 * All of the dinosaurs help zombies to get towards the Player's House except for the pterodactyl; who does the opposite instead.
 * Apparently the maximum species of dinosaurs encountered in a single level is three, except for the boss fight against Zombot Dinotronic Mechasaur, which has all dinosaurs.
 * By Day 15, an asteroid (the note) was found, and Penny believed that it was the meteor that killed the dinosaurs, but shrunk. However, by Day 32, she detects an incoming meteor, meaning that her early speculation was wrong.
 * Before leaving Jurassic Marsh, Crazy Dave says "Bye-bye, dinos! You'll be birdies in no time.", foreshadowing the evolutionary change of the raptors into modern birds.
