Kentrosaurus aethiopicus

A well known member of the Stegosauridae; Kentrosaurus lived during the Late Jurassic, with remains of the animal found in the Tendaguru formation of Tanzania. It was noticeably smaller than many of its relatives, such as the mighty Stegosaurus, but Kentrosaurus made up for this size difference in having a lethal array of spikes running in paired rows down its back to the tip of the tail (which was flexible enough to swing in a 180 degree half-circle behind itself), as well as having large shoulder spines. This would have kept Kentrosaurus well protected from even large predators. Like most stegosaurs, it would have been a low-browser of foliage, but with the center of mass being located in the hip region it could possibly have reared up to feed occasionally, not unlike what some modern ungulates will do.
