Pellegrinisaurus is a genus of titanosaur that lived in South America during the late cretaceous. So far most of the fossils attributed to Pellegrinisaurus are vertebra, however these are mostly from the tail with only a small number of back vertebrae known. This makes an exact size estimate impossible to establish because we can only guess at the back length, while having no idea exactly how long the neck was. Still, we can say that Pellegrinisaurus would have been fairly large and around twenty to twenty-five centimetres long. Even at twenty-fives meters however, Pellegrinisaurus would still pale in comparison to the really large South American titanosaur genera such as Argentinosaurus.
