Dwergallosaurus

"Dwergallosaurus" is an informal name given to a group of carnosaurian dinosaurs that lived during the Early Cretaceous in the south of Australia.

The fossil are interpreted as belonging to a small relative of Allosaurus, a formidable predator of the Jurassic period. "Dwergallosaurus" was probably about two meters high and about six meters long. Until the discovery of this species, it was assumed that Allosaurids had gone extinct thirty million years earlier.
