Kentrosaurus was similar to stegosaurus but was smaller, averaging around 5 meters (16 feet). It also had many more spikes then a spiketail (stegosaurus) had. It also had a large one coming out at the side of each of it's rear hips jutting outward parallel to the ground. Instead of having upright plates on its back as a spiketail (stegosaurus) most of the the plates were actually more spikes.
To date, two species were found. The existence of the species Kentrosaurus aethiopicus is undisputed. Kentrosaurus longispinus (described as Stegosaurus longispinus in 1914 from North America) is not likely to be valid.
The Kentrosaurus was discovered by a German expedition to East Africa in 1909 and 1912 . Edwin Hennig first described this genus in 1915. 
It had a very large body and a huge stomach to eat rough and short plants. The front legs were much shorter than the rear, forcing the Kentrosaurus to walk on all fours. If it had tried to stand up on its own weight it would have to get on all fours again. Yet it is possible that Kentrosaurus could temporarily be on its hind legs to reach shrubs and plants.
Kentrosaurus in The Land Before TimeEdit
Numerous of Kentrosaurus have appeared in The Land Before Time franchise. Kentrosaurus made it's first debut in The Land Before Time VII: The Stone of Cold Fire where one followed Pterano to find a way to the Great Valley along with many other dinosaurs. A few other Kentrosaurus also appear in movie as well. It makes appearances in the TV series episode March of the Sand Creepers.
