== Discovery and naming == The remains were excavated by the Argentine paleontologist Jaime Powell and collaborators in 1984 and described by him in 1987, where he identified the dinosaur remains as a possible "indeterminate lambeosaurine", comparing it mainly with the genera Hypacrosaurus and Barsboldia due to great size of the neural spines.
