Kentrosaurus

Kentrosaurus aethiopicus was a small stegosaur, smaller than  Stegosaurus armatus. The total length of a composite skeletal mount in the Museum für Naturkunde Berlin, Germany, from the tip of the snout to the tip of the tail is 15 ft. Slightly more than half of this length is made up by the tail. Larger single elements were found, so that the animal could probably attain a total length of 18 ft.
