| — Allen, about Stegosaurus|
in Time of the Titans
Stegosaurus (steg-oh-saw-us; meaning "Roof Lizard"), was a stegosaurian dinosaur from the Late Jurassic Period. It is characterized for its distinctive spinal plates and thagomizer. It was the largest of the Stegosauria. It was 10-12, stood over 3-5 meters tall, and weighed 3-7 tonnes.
Stegosaurus is one of the most easily-identifiable/recognizable dinosaurs, due to the distinctive double row of its tall, kite-shaped plates rising vertically along its arched back and the two pairs of long spikes extending horizontally near the end of its tail. It was also one of the least intelligent dinosaurs - it had a brain the size of five walnuts!
Stegosaurus was a heavily-armored herbivore dinosaur that stood 14 feet tall (17 feet at the tallest plate), measured about 36 feet in length, and weighed 7 tons.
Stegosaurus is famous for their distinctive row of 17 large spinal plates on their backs, which were primarily there for display rather than defense, which would be an odd place for armor. The function of the plates has been much debated. Initially thought of as some form of armor, researchers have also proposed that they may have helped to control body temperature. Wind tunnel tests have suggested that the plates are well shaped to gather and dissipate heat.
But it was the four, lethal, meter long spikes on the end of their tails that made Stegosaurus such a lethal dinosaur. Known for being one of the most identifiable dinosaurs, its spikes near the end of its tail were, without question, one of the most dangerous weapons ever evolved by a plant eating animal, let alone, a dinosaur. Such a weapon appears as necessary, considering Stegosaurus coexisted with large predatory theropod dinosaurs, like such as the fearsome Allosaurus. Stegosaurus could weal those spikes with devastating effect, despite having a very small and remarkably tiny brain, at only 80 grams, for their body size, which is what they were also known for, despite their hefty size, and was apparently sufficient for their needs.
Stegosaurus generally lived in pairs, but they have been known to have travel in small herds as well. They also were often solitary creatures, sometimes they ate, drank, and even traveled by themselves.
Although Stegosaurus was a herbivore, they were dangerous creatures. Whenever they faced predators, Stegosaurus could flush blood into their plates and that created a colorful but terrifying display, which was capable of confusing and intimidating even a fully grown Allosaurus. But when attacked, Stegosaurus wielded the spikes on its tale with devastating effect. Stegosaurus was a species of dinosaur that stood and fought with lethal spines.
