What is another word for seismosaurus?
Pronunciation: [sˌa͡ɪzməsˈɔːɹəs] (IPA) 
Seismosaurus is an obsolete genus of sauropod dinosaur that has been at the center of controversy for quite some time. Its name means "earthquake lizard," which suggests how the massive creature could have caused tremors as it walked. However, the genus name has now been replaced by the more accepted title of Diplodocus. Diplodocus is a member of the family Diplodocidae, a group of long-tailed sauropods that lived during the Jurassic period. Other synonyms for Seismosaurus include Seismosaurus hallorum and Ultrasauros, which are also extinct genera of sauropod dinosaurs that were later considered invalid and replaced by Diplodocus and other closely related genera.
