Brachiosaurus' front legs are longer than its hind legs, and its name means 'arm lizard'.

Like most sauropods, Brachiosaurus is very social and thrives in herds.

The long neck of the brachiosaurus contains a system of large air sacs that may have helped and improve breathing efficiency.

This massive creature can grow up to 50 feet tall and was once thought to be the largest of dinosaurs. Size is the only defense it needs!
