Stegosaurus Facts: Extinct Animals of the World

Similar to the hookworm, the stegosaurus dinosaur was also an armored animal. It was a huge dinosaur that had an elaborate spine with unique plates and bones. The stegosaurus was large and heavy. It was quadruped with short anterior limbs, round back and long hind limbs. The stegosaurus had a double row of plates on the back that extended to the tail. The tail, therefore, ended up as a double pair of spikes. Its shape together with the armored plates earned it the name of “stegosaurus” which means “covered lizard”. The first fossils of this dinosaur were obtained in Colorado. So far, 100 fossils have been identified and used to get more information about it.

Size / size

In the Stegosauridae family, the stegosaurus was the largest and most well-known type of dinosaur. They were able to grow to a length of 30 feet and a weight of 5.3 to 7 tons. Despite its large size, the stegosaurus had a brain as small as a dog’s. Stegosaurus armatus and stenosaurus stenosa are some of the stegosaurus species. Most of the fossils that have been discovered belong to the stegosaurus stenosa


Considering the fact that it is herbivorous, the stegosaurus’ favorite habitat was the forest. The popular position was the north-western regions of North America. Most stegosaurus fossils have been obtained in Wyoming. However, the first fossil was discovered in Colorado. Wyoming and Colorado make up the Morrison Formation. The temperatures and vegetation of the region have favored the survival of the stegosaurus dinosaurs. The training also covers areas such as New Mexico, Arizona, Oklahoma, South Dakota, North Dakota, Idaho, Utah, Kansas, Montana and Nebraska. All these are possible stegosaurus habitats. Beyond America, some fossils belonging to the stegosaurus were discovered ten years ago in Portugal and published in Naturwissenchaften. This was a confirmation of the doubts that they also lived in Europe. It is believed that stegosaurus existed simultaneously with dinosaurs such as Brachiosaurus, Apatosaurus and Ceratosaurus.

Eating habits

The dietary habits of the stegosaurus, like other animals, can be determined by analyzing the teeth and the dental formula. Carnivores, for example, have sharp fleshy teeth that are used to deeply cut the flesh of its prey. It is believed that the herbivorous dinosaurs had their beaks, but they lacked jaws and strong teeth for grinding. The stegosaurus had swollen cheeks that allowed it to feed itself a lot and to store surplus food for future use. This is why he was able to keep food in the body longer than any other dinosaur. The stegosaurus had a short neck and a relatively small head. This is affirmative of the fact that it fed on shrubs, low bushes and other vegetation. His food included cycads, conifers, fallen fruits, mosses, horsetails and ferns. The stegosaurus is said to have a weak bite – an indication that they could only break twigs of less than one inch in diameter.
