Living: The Kentrosaurus lived near a prehistoric river, where the air always was warm, and rainy periods alternated with droughts. The Kentrosaurus could always find food growing in the moist soil near the river. It moved around on four limbs and had a short neck. Therefor scientists have concluded that it ate low-growing plants. However, it might have raised up on its strong limbs and reached leafy twigs. It defended itself from dangerous enemys like the Allosaurus and Ceratosaurus by backing into the enemy or by lashing it tail from side to side.
Tailbones: Most of the Stegosaurus-like dinosaurs had their spikes pointing backwards, but the Kentrosaurus had, from its 18th tail-vertebra, spikes, which pointed forward. An other difference is that its chevron had the shape of a plow.
The brains: The scientists thought that the family stegosauridae to whom the Kentrosaurus belonged had two brains, one placed in its skull, while the big one was in its pelvis. But the second brain was a nerve relay station controlling the hind limbs and tail.
