Kentrosaurus is a herbivorous dinosaur known for its rows of plates and spikes along its back and tail and inhabited various regions during the Late Jurassic period, approximately 156 to 150 million years ago. Fossils of Kentrosaurus have been discovered in locations such as Tanzania, Africa, where evidence of this dinosaur's existence provides valuable insights into the adaptations and diversity of herbivorous dinosaurs during the Jurassic era. Measuring around 4 to 6 meters (13 to 20 feet) in length and weighing an estimated 1 to 2 tons, Kentrosaurus played a significant role in dinosaur evolution and paleontology, contributing to our understanding of prehistoric ecosystems and the unique characteristics of stegosaurian dinosaurs.
