A large long-necked dinosaur with unusually long front legs, making it look like it's reaching upward, famous for being one of the biggest land animals ever to exist.
From Greek 'brachion' (arm) and 'sauros' (lizard), literally 'arm-lizard'. The term references the dinosaur's distinctive long front limbs, which were longer than its hind legs, an unusual feature among dinosaurs.
