A skeletons tells a story. Teeth or bony beaks give information about what dinosaurs probably ate. Features such a horns show how they defended themselves. Small braincases tell us which dinosaurs had small brain.
Spiky plant eater
A Late Jurassic dinosaur, Stegosaurus was probably about 3m (9ft) high. It had bony plates along its back. Its spiky tail was flexible and most likely used for defence.
Small sprinter
A fossilized skeleton shows that Coelophysis had long legs for its small size. It was 3m (9ft) long and could run fast.
Massive meat eater
Meat eaters like Tyrannosaurus rex had massive jaws. They could open these extra wide to swallow large mouthfuls of fresh.
Jurassic giant
The longest of all dinosaurs, sauropods like Diplodocus had small brains! Despite its length, Diplodocus weighed no more than two large elephants.
Bird like dinosaur
A fossilized skeleton of Struthiomimus shows that it had features in common with todays ostrich. These include a small head with a narrow beak, a long neck, and powerful hind limbs.
Horned head
The Late Cretaceous Triceratops was haunted by Tyrannosaurus rex. It probably used its horns to defend itself. A plant eater it had a tough, toothless beak.
