Beyond the game
The real Irritator
The skull used to name it was acquired from fossil dealers and described in 1996. This origin complicated the study and gave rise to a prolonged discussion about its return to Brazil.
It is known from an almost complete skull from the Araripe Basin in Brazil. This origin complicated its study and the history of the specimen. Knowing where a piece comes from and how it was collected is part of the scientific information that accompanies the bones.
