Kentrosaurus is closely related to Stegosaurus but it is smaller, end the paired plates along its back give way to pairs of tall spines over the hips and long tail. This is why it is called the 'Spiky Lizard'.
Kentrosaurus was found in 1909, in Tanzania by a German expedition. Hundreds of bones of about 70 individualls were recovered. From these bones the scientists could build two complete skeletons. Sadly one of them was completely destroyed when a bomb hit the Humboldt Museum in Berlin, during the Second World War.
Like Stegosaurus, Kentrosaurus had a long, narrow head. It had a horny beak for cutting and slicing plant material and many small teeth, behind the beak, for more crushing and grinding. The huge number of bones found during the original expedition suggests that Kentrosaurus lived in herds near lakes and rivers. They lived at the same time as the Elaphrosaurus (‘Lightweight Lizard’) and several meat eaters. These may have been Kentrosaurus's natural enemies, but it is most likely that 70 individuals died as a result of some natural disaster such as a flood.
