Stegosaurus

With a massive, hulking body complete with a powerful tail and sharp spines all along its back, it's no wonder the stegosaurus is perhaps the most well-known and commonly recognized herbivore dinosaur of all time. Stegosauruses existed somewhere around 150 million years ago, during a period in history known as the late Jurassic period. Despite being herbivores, the dinosaurs had a rather intimidating appearance. The name Stegosaurus translates to "covered lizard, in reference to the hard plates its body possesses. The function of this variety of plates and spikes has been the subject of much theory and debate. Researchers in the paleontological community assume that their spiked tails were no doubt utilized for barrier against predators, while their plates may have been just for show, and possibly also for temperature regulation within the body. These were very adjusted osteoderms (hard cored scales), like those found in crocodiles and some other types of modern reptiles. As you know, Stegosauruses and related species were herbivores, but their teeth and jaws were rather unique when compared to those of other herbivores, such as those of other herbivorous "ornithischian"(meaning having a similar pelvic structure to birds) dinosaurs, suggesting they used a different feeding strategy, one that is not yet well understood. Normally, stegosauruses grew to a length of about twenty-one feet but some reached thirty feet. Stegosaurus and its relatives are closely related to the ankylosaurs, with which they share dermal protection as well as numerous other traits, such as a bent column of little teeth. The two species were developed from ancestors of smaller armored dinosaurs, such as the Scelidosaurus and the Scutellosaurus of the Early Jurassic Period (206 million to 180 million years ago). The plates that are seen on different types of stegosauruses varied: some forms seem to have had parallel plates instead of alternating plates, and a few, like the Kentrurosaurus, had plates all along the front half of the back, but then spikes along the back half which continued to the tail. Stegosaurus fossils have namely been found across the western sections of North America. There is some evidence to indicate they also lived across western Europe, as the fossils have also been found in Portugal. The brain of a stegosaurus compared to its body mass is incredibly small, around the size of a walnut, which would be about the size brain a small dog would possess. The tail spikes of a stegosaurus protruded about two feet straight up. Combined with their thick and powerful nature, it is easy to see why some scientists theorize these spikes were used for self-defense. The trademark plates a stegosaurus had on its back protruded directly from the skin rather than starting in the skeleton, and are estimated to have been around two and a half feet tall and about the same area in length. Despite not having all the predatory traits of the menacing tyrannosaurus rex, the stegosaurus is still an incredible and well-known dinosaur.
