Haplocanthosaurus was a medium-sized sauropod dinosaur that lived during the late Jurassic period. The name means \"single-spined lizard\". It was first named \"Haplocanthus\" by John Bell Hatcher; however, he later realized that it sounded like a genus of a fish. John eventually became concerned about the name for this reason, so the name was changed from Haplocanthus to Haplocanthosaurus.<\/p>\n\n\n\n
It was one of Morrison's smallest sauropods and reached a total length of only 14.8 meters, while some of the same family could reach more than 20 meters. It was a four-legged dinosaur and had a long tail and neck. Like other sauropods, its main food source was probably conifers, ginkgos, seed ferns, cycads, bennettitalean, ferns, clubmoss, etc. Horsetails were secondary foods. Little else is known about this dinosaur.<\/p>\n\n\n\n
