The tallest and heaviest dinosaur known from good skeletons is "Giraffatitan brancai" (previously classified as a species of "Brachiosaurus"). Its remains were discovered in Tanzania between 1907 and 1912. Bones from several similar-sized individuals were incorporated into the skeleton now mounted and on display at the Museum für Naturkunde in Berlin; this mount is tall and long, and would have belonged to an animal that weighed between and  kilograms ( and  lb). The longest complete dinosaur is the long "Diplodocus", which was discovered in Wyoming in the United States and displayed in Pittsburgh's Carnegie Museum of Natural History in 1907. The longest dinosaur known from good fossil material is the "Patagotitan": the skeleton mount in the American Museum of Natural History in New York is long. The Museo Municipal Carmen Funes in Plaza Huincul, Argentina, has an "Argentinosaurus" reconstructed skeleton mount that is long.
