GIANT DINOSAUR
One of the biggest dinosaurs ever discovered, the brachiosaurus had 12 neck vertebrae,
each about 2½ feet
long. Like a giraffe, this dinosaur probably used high blood pressure and a strong
heart to pump blood to its brain - 30 feet up! It gets the name "arm lizard" from
its unusually long front limbs, which are longer than its back legs.
