Irritator was the first Spinosaurid discovered in the Americas. It is from South America moreover, which had been connected to Africa at this time. As the name suggests, something was irritating about Irritator. This was because the people (fossil 'poachers') who discovered its skull added fake bits and rendered it with plaster of paris to make it look prettier, and the team of Palaeontologists led by British Palaeontologist Dr. David Martill (Lecturer at Portsmouth University) got irritated trying to work out what was fake and what was genuine, as well as the cleaning up needed to be done on the plaster of paris which in itself was very time consuming and ultimately should not have had to be done.

Irritator was 25-35 ft long and would perhaps have weighed 1.5-3 tonnes. Its diet is mainly fish. A remarkable pterosaur fossil from South America of a section of neck vertebrae from Anhanguera, has a bite mark and embedded tooth - which is of a spinosaurid and likely belonged to Irritator or a relative. This shows Spinosaurs could actively attack even highly agile and aerially mobile animals like pterosaurs, not just hunt fish. Adding this knowledge to that we know of spinosaur bites and teeth in relation to juvenile Iguanodon from England (Baryonyx and Becklespinax as the culprits) then we can build a picture of spinosaurs as not just being fish eaters. They could hunt dinosaurs and Pterosaurs as well.

Irritator's binomial name, challengeri, refers to the Professor Challenger of the original novel by Sir Arthur Conan Doyle on 'The Lost World', as his famous fictitious expedition was to a South American plateau, something which evokes similar thoughts when studying this South American Spinosaur.
