Irritator is a genus of spinosaurid dinosaur that lived in the early Cretaceous Period, around 110 million years ago. Current estimations indicate a length of 8 meters. In 2010, Gregory S. Paul gave lower estimations of 7.5 meters and one ton.
Irritator is the third cheapest Rare Carnivore. It also has the shortest hatching time for rare dinosaurs. A Hybrid, Diplotator, can be made by fusing Irritator and Diplocaulus. Irritator is often considered the weakest of the Rare Carnivores due to its low health; it is also directly outclassed by Pyroraptor, Tyrannotitan, Carnotaurus, Ophiacodon, and Monolophosaurus. It can be unlocked by beating battle stage 41.
