"Dinos A to Z: Kentrosaurus" introduces the Kentrosaurus, an armored herbivorous dinosaur that lived about 155 million years ago. The video explains its name, physical features, spikes, size, weight, and defensive adaptations, while comparing it to its relative, Stegosaurus. It also covers fossil discovery in Tanzania by Werner Janensch in 1909, key paleontology terms such as vertebrae and fossils, and how scientists infer diet, behavior, and ecosystem role from fossil evidence. With clear dinosaur vocabulary, prehistoric life facts, and connections to earth and life science, this resource supports curriculum topics in paleontology, evolution, habitats, and scientific observation.
