Traukutitan is a genus of titanosaurian dinosaur that lived in South America during the late Cretaceous. Traukutitan was named after Trauku, an Araucanian mountain spirit. The species name T. eocaudata is a reference to the primitive appearing form of the caudal vertebrae. There is speculation that Traukutitan was a lognkosaurian titanosaur, and this might fit given that lognkosaurians are well known from South America during the Santonian stage of the Cretaceous.
