Brachiosaurus - the largest of the dinosaurs?

With a total length of 85 feet (!) and weighing in around 70,000 pounds, calling Brachiosaurus large would be a big understatement to say this was a large animal. Most resembling a modern day giraffe, this herbivore was just simply huge. Brachiosaurus is from a genus of sauropod dinosaur from the Jurassic Morrison Formation of North America.
