**Stegosaurus**

Stegosaurus is one of the most iconic and well-known dinosaurs, belonging to the genus *Stegosaurus* and the Stegosauria clade. It lived during the Late Jurassic period, approximately 155 to 150 million years ago, in what is now North America, including regions of what are now the United States and Canada. Fossil evidence suggests it inhabited a variety of environments, including forests, grasslands, and river valleys.

Stegosaurus is distinguished by its unique body armor, featuring rows of large, plate-like structures called thagomizer plates along its back. These plates, typically around 20 in number, were likely used for display, thermoregulation, or defense. In addition to the plates, it possessed a pair of spiked tail clubs, which may have been used for combat or defense against predators. The exact function of these features remains a subject of scientific debate.

Stegosaurus was a quadrupedal herbivore, primarily feeding on plants. Its skull was small compared to its massive body, which suggests it may have relied on a variety of feeding strategies, such as browsing or scraping vegetation. The animal had a long neck and a small head, with a beak-like mouth adapted for eating foliage.

Fossil remains of Stegosaurus have been extensively studied, with numerous well-preserved specimens discovered, particularly in the western United States. The discovery of its remains helped shape early perceptions of dinosaurs as slow-moving, plant-eating creatures. However, recent research has suggested that Stegosaurus may have been more active and agile than previously thought, with some evidence indicating it could have been a fast runner.

Stegosaurus is often depicted in popular culture, symbolizing the era of the Jurassic period and contributing to the broader fascination with prehistoric life. Its distinctive features continue to captivate paleontologists and the public alike, making it a enduring figure in the study of dinosaurs.
