DESCRIPTION: Kentrosaurus was a slow-moving herbivore (plant-eater) that lived in Africa during the
late Jurassic Period, about 156 to 150 million years ago. Kentrosaurus may have been slow-moving, but
it was well protected from predators by its armor. Its back was covered with a double row of triangular
bony plates on each side of the backbone. At the rear, the plates were then replaced with pairs of sharp
spikes, about 2 feet (60 centimeters) long, that went from the lower back down to the tip of the tail.
