Ultrasaurus (meaning "ultra lizard" [2]) is a genus of sauropod dinosaur discovered by Haang Mook Kim in South Korea. However, the name was first used unofficially (as a nomen nudum ) in 1979 by Jim Jensen to describe a set of giant dinosaur bones he discovered in the United States.
The primary source for this list is a book called Dinosaur Facts and Figures: The Sauropods and Other Sauropodomorphs by Rubén Molina-Pérez and Asier Larramendi which contains every sauropodomorph species described up to the date of its completion (January 1, 2019), including dubious or very fragmentary specimens.

James Alvin Jensen (August 2, 1918 – December 14, 1998) was an American paleontologist.His extensive collecting program at Brigham Young University in the Utah–Colorado region which spanned 23 years was comparable in terms of the number of specimens collected to that of Barnum Brown during the early 20th century.

Dreadnoughtus is a genus of titanosaurian sauropod dinosaur containing a single species, Dreadnoughtus schrani. D. schrani is known from two partial skeletons discovered in Upper Cretaceous (Campanian to Maastrichtian; approximately 76–70 Ma) rocks of the Cerro Fortaleza Formation in Santa Cruz Province, Argentina.
Ultrasauripus is an ichnogenus of dinosaur footprint, found in Gyeongsang Province, South Korea.Ιn 2020 Molina-Pérez and Larramendi, based on the 1.24 meter (4 ft) long footprint, estimated the size of the animal at 27–34.5 meters (88–113 ft) and 55 tonnes (60 short tons).
Based on surviving descriptions of a single fossil bone, scientists have produced numerous size estimates over the years; the largest estimate M. fragillimus to have been the longest known animal at 58 metres (190 ft) in length with a mass of 150 tonnes (150 long tons; 170 short tons). However, because the only fossil remains were lost at some ...
Eoraptor (/ ˈ iː oʊ ˌ r æ p t ər /) is a genus of small, lightly built, basal sauropodomorph dinosaur.One of the earliest-known dinosaurs and one of the earliest sauropodomorphs, it lived approximately 231 to 228 million years ago, [1] during the Late Triassic in Western Gondwana, in the region that is now northwestern Argentina.
