It was first described and named by Ricardo N. Martínez, Cecilia Apaldetti, Carina E. Colombi, Angel Praderio, Eliana Fernandez, Paula Santi Malnis, Gustavo A. Correa, Diego Abelin and Oscar Alcober in 2013 and the type species is Sphenotitan leyesi.[1] LifestyleBased upon the dentition seen in the fossil specimens, this animal is believed to be herbivorous.[1] References1. ^1 {{Cite journal | last1 = Martinez | first1 = R.
