Sonorasaurus was a brachiosaurid dinosaur from the middle Cretaceous. It was a herbivorous sauropod. and its fossils have been found in southern Arizona, USA. Its name comes from the Sonoran Desert where its fossils were first found, i.e. "Sonora lizard".
It is estimated to have been about 50 feet long and 27 feet high, about one third of the size of Brachiosaurus.
Fossilised remains were discovered by geology student Richard Thompson, in 1995, in the Chihuahua Desert region of the Sonora Desert in southern Arizona, USA. Ageing of the find makes this the first known brachiosaur to have lived in the middle Cretaceous Period of North America.
