Brachiosaurus
"Arm Lizard"

 

ANATOMY
Brachiosaurus was one of the tallest and largest dinosaurs yet found.
It had a long neck, small head, and relatively short, thick tail. It
 walked on four legs and, like the other Brachiosaurids and unlike
most dinosaurs, its front legs were longer than its hind legs. These
unusual front legs together with its very long neck gave
Brachiosaurus a giraffe-like stance and great height, up to 40-50 feet
 tall (12-16 m). Brachiosaurus was about 85 feet long (26 m), and
weighed about 50-80 tons. Like other Brachiosaurids, it had
chisel-like teeth, its nostrils were on the top of its head, and it had
large nasal openings indicating that it may have had a good sense of
smell. Brachiosaurus had 26 teeth on top jaw and 26 on the bottom
for a total of 52 teeth. It had a claw on the first toe of each front foot
and claws on the first three toes of each rear foot (each foot had five
toes with fleshy pads).
