Size: 26 – 28 Feet
Weight: 1 – 2 Tons
Habitat: Carnian Swamps, Grand River, Hushed Forests


Irritator was one of the smallest Spinosauroids and it had a small back sail like its brethren. It had a generalist diet and preyed on both fish and small to medium sized terrestrial prey.

Paleo Chronicles

Irritator lived in the early Cretaceous period and was small when compared to others in its family. It was 26 – 28 feet long and weighed 1 – 2 tons. Like all Spinosauroids it preyed on anything it could get a grab on and this is supported by the presence of an irritator teeth in the neck column of a large pterosaur. It likely had well developed forearms and used them for both combat and predation.

In Game Attributes

Irritator has the highest health and fastest swim speed in its class. It is however slower than the others in its class and has lower damage as well. It can dive deep for longer periods of time than Oxalaia and it is unaffected by the speed debuff in the swamps as well.
