Stegosaurus was a large armored plant-eating dinosaur that lived during the Upper Jurassic Period (155-150 million years ago) in what is now western North America. It had an unusually small head, and although an adult would have weighed over 4.5 metric tons, its brain would have weighed less than three ounces. This led to the suggestion that Stegosaurus was extremely dull-witted, but it was clearly a successful dinosaur, so its small brain obviously wasn’t a problem.

  • Scientific Name: Stegosaurus, meaning ‘covered lizard’ for the bony plates that covered its back.
  • Characteristics: Stegosaurus has extremely short front limbs that gives it a very rounded back and places its small head very close to the ground. Because of this, it is thought that it would have been restricted to feeding at or near ground level. Stegosaurus has two sets of long bony spikes on the tail that probably functioned in defense against predators, and a double row of plates along its back.
  • Size and Color: This model is 12.25 inches long and 6.5 inches high. It is mostly brown and red earth tones with some yellow, allowing the animal to blend into its surroundings.
  • The Stegosaurus is part of the Great Dinos collection

Stegosaurus skeletons were collected in Colorado in the 1870’s by two famous American paleontologists, Othniel Marsh and Edward Cope. There two men were fierce competitors, each trying to find more dinosaurs than the other. Because of this competition, many different species of dinosaurs were collected in Colorado, including skeletons of Stegosaurus, Apatosaurus, Diplodocus, Brachiosaurus, Allosaurus, and Ceratosaurus. These dinosaurs all lived in the Late Jurassic, with the meat eating Allosaurus and Ceratosaurus feeding on the herbivorous Stegosaurus, Apatosaurus, Diplodocus and Brachiosaurus.

It was once thought that these were also for defense, but now we believe that they were for display – to intimidate other Stegosaurus, or perhaps to attract mates. It is also possible that they used them to absorb sunlight to warm the body in the morning, or even to radiate heat if the body became too warm, much like some butterflies use their wings today.
