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.
Length: 3-4 meters
Height: 1-1.2 meters
Weight: 100-400 kg
Gasosaurus would probably have fed mostly on small to medium sized animals, but could theoretically have even taken down primitive sauropods. Perhaps it could accomplish this by using pack-hunting.
