Dinosaur stegosaurus (Pronoun: STEG-oh-SAW-rus), it means a cover lizard. They lived in the Jurassic period 150 to 145 million years ago. Even though stegosaurus is a herbivore, eating mainly low level ferns, they are relatively large. Mature dinosaurs can grow up to 12 meters long and weight up to 7 tons.
Fossil remains found saw a wide distribution of Stegosaurs from the United States (Colorado, Utah, and Wyoming), Western Europe, China and Southern Africa.
From the skeleton remains stegosaurus had four sturdy legs and a line of plates running down its back. They had noticeably longer and straighter back legs and a powerful beaked like mouth for cropping up vegetation.
Stegosaurus has a short and muscly tail with four 1 meter long spikes which is used as a formidable tail. To protect the throat area there are a series of bones under the neck that acts as a chain mail.
The actual role of the plated armour is unknown. It could be used as armour to protect, act a form of heat control or just for display. Many palaeontologists believed that is were only used for display by putting off attackers and for attracting a mate.
