This Canon Papercraft is a Supersaurus, designed by Ayumu Saito. The name Supersaurus means 'super lizard' and the dinosaur belongs to four-legged, plant-eating (Sauropoda) group of dinosaurs that have lizard-like skeletons (Saurischia).
Supersaurus was discovered when a huge shoulder blade, measuring over 2 meters in height, was found in the Dry Mesa quarry in the U.S. state of Colorado. Until 1979, giant fossils, believed to be from the same animal, continued to be found. Then, in 1985, Dr. Jim Jensen, realizing that it was a dinosaur much bigger than even the Brachiosaurus and Diplodocus, at that time thought to have been the largest dinosaurs, named it 'Supersaurus'. It had a very long neck and a snake-like tail that it is believed to have used like a whip to protect itself. Dinosaurs lived about 225 million years ago, in the Mesozoic era, which is made up of the Triassic, Jurassic and Cretaceous periods. It is thought likely that the dinosaurs were wiped out around 65 million years ago, when many plants and animals died as a result of climatic changes brought about by a meteor striking the earth, but no one knows what really happened.
