Pellegrinisaurus (meaning "Lizard from Pelligrini") is the name given to a genus of dinosaur from the Late Cretaceous. It was a titanosaur which lived in what is now Argentina, found in the Anecleto and Allen Formations, stretchering the range of Pellegrinisaurus from early to late Campanian in age. The type species, Pellegrinisaurus powelli, was described by Salgado in 1996, and is based on mostly vertebrae. Pelligrinisaurus is estimated to have been between 62–78 feet in length, but because a full fossil skeleton has not been recovered, this is only a rough estimate.
