Giraffatitan was originally described as Brachiosaurus brancai in 1914 based from a partial skeleton discovered in Tanzania, until a revaluation of the specimen in 1988 by Greg Paul determined the specimen differed from other Brachiosaurus material and warranted a separate genus. The specimen in question is on display in the Berlin Naturkundemuseum (Museum of Natural History). As this specimen was once considered the most complete Brachiosaurus known, most artist reconstructions of Brachiosaurus are based on the Berlin specimen thus they are actually Giraffatitan!
