Page 59 - Everything You Know About Dinosaurs is Wrong

When palaeontologists describe new types of dinosaurs only to find out later that they were the same as dinosaurs that had already been discovered, the new names they invented become extinct.
During the Bone Wars, many other dinosaurs were named that weren’t really new types. ‘CREOSAURUS’, described in 1878, was really just an ALLOSAURUS.
This happened in the twentieth century too. ‘BRONTORAPTOR’ was described in 1996 but was later found to be a fossil of the Late-Jurassic theropod TORVOSAURUS.
Sometimes palaeontologists only find one bone and name a whole new dinosaur. ‘ULTRASAUROS’ was named after a huge back bone that was later worked out to have actually belonged to the gigantic SUPERSAURUS. Oops!
