Brachiosaurus brancai stands 13.27 metres tall and is the tallest mounted dinosaur skeleton in the world, as the Guinness Book of Records confirms. The dinosaur lived 150 million years ago and fed on plants. Its skeleton was found by researchers during the great Tendaguru expedition. The name Brachiosaurus – lizard with arms – refers to its long arms.
A new scientific name was given to Brachiosaurus in 2009, when differences in the shape, size and proportions of the bones led to the distinction between a North American and an African Brachiosaurus genus. Thus, Brachiosaurus brancai became Giraffatitan brancai. This is now the scientifically recognised name used by researchers.
