The type species, Fulgurotherium australe, was named and formalised by Friedrich von Huene in 1932 but the animal may be a chimera based on multiple species of Ornithopods. The genus name is derived from Latin, Fulguro, meaning "lightning", and Greek, therium, meaning "beast", a reference to the Lightning Ridge site in New South Wales. The specific name means "southern" in Latin. The holotype is BMNH R.3719, which is the opalised lower end of a femur, indicating a total body length of 1 to 1.5 metres. Von Huene thought it was a theropod, a member of the Ornithomimidae.
It has later been described as a hypsilophodont, a primitive ornithopod. However, this was based on a contentious reference of bones found in the Dinosaur Cave, leading to a possible confusion between multiple species of Euornithopoda. Most researchers today consider it a nomen dubium. Fulgurotherium was a hypsilophodont, a primitive ornithopod.
