Futalognkosaurus (meaning "giant chief lizard") is a genus of titanosaurian dinosaur. Its fossils were found in the Neuquén province of Argentina in 2000, and were scientifically described in 2007. The genus name is derived from the local indigenous language Mapudungun and is pronounced foo-ta-long-koh-sohr-us: "futa" means "giant" and "lognko" means "chief". The type species, Futalognkosaurus dukei, is estimated to be between 32 and 34 meters (105-111 ft) in length. It is based on three fossil specimens, yielding an estimated 70% of the skeleton in total. The fossil team described the find as "the most complete giant dinosaur known so far". The herbivorous Futalognkosaurus lived approximately 87 million years ago in the Coniacian stage of the late Cretaceous Period.
