.
Lambe assigned two new skulls to T. marginatus, and based on the new information, coined the genus Stephanosaurus for the species in 1914.type specimen of Stephanosaurus was the original, scrappy limb bones and crushed skull fragments, not the two new skulls.
However, the limb bones and skull fragments could not be reliably said to come from the same animal as the complete skulls, or differentiated from other hadrosaurs. Because there was very little to associate the complete skulls with the scrappy earlier marginatus material, in 1923
type specimen NMC 2869, originally GSC 2869). Stephanosaurinae, a group which Lambe named in 1920, was also renamed Lambeosaurinae.[4]
