Most dinosaurs' names come from Latin or Greek words. Sometimes, they are named for the person who discovered them, or the place they were discovered, like Minmi. A few dinosaurs are simply named after English words, like Irritator, and the early Jurassic carnivore, Gasosaurus, literally meaning "gas lizard." The small dinosaur's name does not imply that it ate a lot of beans, but that it was discovered in China during the construction of a gas factory. This dinosaur is an early "tetanuran" which is the group containing advanced theropods, making it an early relative, and possibly even ancestor of such monsters as Allosaurus, and T-rex.
