Brachiosaurus

Brachiosaurus or (arm lizard) is one of the largest sauropods in the late Jurassic period.

Appearance
Brachiosaurus has a nasal echo chamber at the top of its nostrils to emit an tremendously loud call. Brachiosaurs may have blunt claws and teeth, and a short tail, but they can be self-defensive if they are big enough to fend off attackers.

Attacks
Brachiosaurus' main strength is size. It can stagger opponents by kicking them out of its boundaries, whip away attackers with its long tail, or trample them flat in its way.
