Stegosaurus is a type of dinosaur that lived during the Late Jurassic Period, around 155 to 150 million years ago. It was a herbivore, which means it only ate plants. Stegosaurus had a distinct appearance with its large size and unique body features. One of the most recognizable features of Stegosaurus is its row of bony plates that ran along its back. These plates were used for display and possibly for regulating body temperature. They could also provide protection against predators.

Another notable feature of Stegosaurus is its tail, which had several long, pointed spikes. These spikes, known as thagomizers, were used for defense against predators. Stegosaurus had a small head with a beak-like mouth, and it likely fed on low-growing vegetation. It had a relatively small brain compared to its body size.

Stegosaurus lived in habitats with abundant vegetation, such as forests or open woodlands. It likely lived in herds and had a slow, lumbering gait. The purpose of Stegosaurus’ unique plates and tail spikes are still debated among scientists, but they are believed to have played a role in defense, thermoregulation, or display.
