Dracosaurolophus

Dracosaurolophus, name meaning dragon lizard crest, is an extinct species of ornithopod Hadrosaur that lived in what is now North America during the Late Cretaceous period. It was the first ever dinosaur to be confirmed to have fire breath, a feature once thought to be a myth, since scientists that studied the crest that was similar to that of a Parasaurolophus, they had discovered that it had some chemicals to allow fire, so it could breath fire at its predators like a mythical dragon. Despite its fire breathing ability, it was a gentle herbivore that fed only on leaves, ferns, horsetails, cycads, and other leafy plants. It was also about the same size as a Hadrosaurus. It might had went extinct due to the effects of an asteroid impact and its effects during the K-T mass extinction.
