Celebrating a Life: The Irritator
In loving memory of Ira Tator. 144-127 million years B.C.E.
The Irritator challengeri Species
Irritator challengeri was one of the most interesting looking dinosaurs found. Many people wondered why this fine creature has such a crude name. The scientists obtained its skull from a commercial fossil dealer. All the scientists were shocked by the size of the snout, and they had good reason to. The fossil dealer who gave it to them had artificially elongated the skull. The scientists then had the tedious task of sorting real skull from the rest of the clay and other materials made to make the skull larger. This intriguing species sadly died out about 127 million years ago and lived during the Mesozoic period. The species did thrive for a good 17 million years, though. Irritator was found in Brazil. This dinosaur is closely related to the spinosaur, another dinosaur that was large and walked on two legs with two arms on top. Irritators were carnivorous and ate many smaller dinosaurs and fish. This animal was about twenty-one feet tall and twenty-five feet long. The head was rather large, about eighty centimeters across, with a snout very similar to that of a crocodile. The species also had a curved spine and growths sticking up from its back.
