context_page_description: Pellegrinisaurus is a genus of titanosaurian sauropod dinosaur that lived in South America during the Late Cretaceous period. The holotype was found in the Allen Formation, Argentina.
context_section_description: The assigned holotype, MPCA 1500, was discovered in 1975 by Roberto Abel and his assistant Jaime Emilio Powell. It was recovered from the lower member of the Allen Formation in the locality of Pellegrini Lake, Argentina, dating from the Late Cretaceous, Campanian to lower Maastrichtian, but it was not formally described until 1996 by Leonardo Salgado. Initially, the recovered remains were referred to Epachthosaurus, but later this hypothesis was abandoned because MPCA 1500 did not share derived features with the holotype of Epachthosaurus. The generic name Pellegrinisaurus refers to Pellegrini Lake, where the specimen was found. The specific name powelli is in honour of Jaime E. Powell.
