bony back
That would describe the Stegosaurus a thyreophoran dinosaur.
The large dinosaur with defensive "plates" down its back is a stegosaurus.(genus Stegosaurus, species S. stenops, S. armatus, S. longispinus)
There was the small head and short neck, which were low to the ground. Stegosaurus had four legs, and its forelimbs were much shorter than its hind limbs. The whole Stegosaurus was covered in skin, and of course it had a tail. There were 17 large, triangular, bony plates that stuck vertically out of the creature's back and there were four spikes protruding horizontally from the end of the tail, two on each side. These thagomizers were used for self defense.
Stegosaurus didn't have horns. It had 17 large, triangular, bony plates that stuck vertically out of its back in two parallel rows, with plates alternating from one row to the other. Whether the plates were useful for defense is debatable. However, the tail of Stegosaurus had four long spikes called thagomizers near its end. The thagomizers would have made very effective weapons and were used to stab predators.
Stegosaurus plates aren't attached to the skeleton. They are connected to the Stegosaurus via the skin.
Spinosaurus had a large sail on its back that was connected to its spine. The sail may have been used for attracting mates, thermoregulation, and a new theory is it may have casted a shadow over a river to attract fish for the Spinosaurus to snatch.
Stegosaurus had plates down it's back
There were a number of dinosaurs that were related to Stegosaurus and also had two rows of plates on their backs. One example is Kentrosaurus, which was a lot like Stegosaurus but lived in Africa. Another example is Hesperosaurus, which was related to the ancestors of Stegosaurus.
Stegosaurus???

You are referring to Stegosaurus. Stegosaurus was a slow, herbivorous dinosaur that had two rows of plates on its back, and four spikes on its tail as a self defense weapon.
