FACTS:
Stegosaurus had 17 bony plates that were embedded in its back - the plates ran along the Stegosaurus' back and tail in two rows, and the plates alternated in alignment. The largest of these triangular plates was about 2.5 ft (76 cm) tall and just as long. Stegosaurus also had spikes at the end of its flexible tail (these are called thagomizers).

Although Stegosaurus was about the size of a bus, it had a small head (the size of a horse's head) and a brain that was only the size of a walnut!
