Supersaurus (meaning "super lizard") is a genus of diplodocid sauropod dinosaur that lived in North America during the Late Jurassic period. The type species , S. vivianae , was first discovered by Vivian Jones of Delta, Colorado , in the middle Morrison Formation of Colorado in 1972.
Ultrasaurus lived 100 to 110 million years ago, during the Aptian and Albian stages of the Early Cretaceous.It is known from the holotype DGBU-1973, which consists of part of an upper forearm (), and DGBU-1978-A, a single tailbone from the Gugyedong Formation, belonging to the Hayang Group.
Argentinosaurus (meaning "lizard from Argentina") is a genus of giant sauropod dinosaur that lived during the Late Cretaceous period in what is now Argentina.Although it is only known from fragmentary remains, Argentinosaurus is one of the largest known land animals of all time, perhaps the largest, measuring 30–35 m (98–115 ft) long and weighing 65–80 t (72–88 short tons).
The largest extant theropod is the common ostrich, up to 2.74 metres (9 ft 0 in) tall and weighs between 63.5 and 145.15 kilograms (140.0 and 320.0 lb). [ 35 ] The smallest non- avialan theropod known from adult specimens may be Anchiornis huxleyi , at 110 grams (3.9 ounces) in weight and 34 centimetres (13 in) in length, [ 36 ] although later ...
The largest animal currently alive is the blue whale. The maximum recorded weight was 190 tonnes (209 US tons) for a specimen measuring 27.6 metres (91 ft), whereas longer ones, up to 33 metres (108 ft), have been recorded but not weighed. [1] [2] [3] It is estimated that this individual could have a mass of 250 tonnes or more.
Ultimately the largest sauropods, like Supersaurus, Diplodocus hallorum, Patagotitan, and Argentinosaurus, reached 30–40 metres (98–131 ft) in length, and 60,000–100,000 kilograms (65–110 US short tons) or more in mass. [citation needed]
Sauropoda is a clade of dinosaurs that consists of roughly 300 species of large, long-necked herbivores and includes the largest terrestrial animals ever to exist. The first sauropod species were named in 1842 by Richard Owen, though at the time, he regarded them as unusual crocodilians.
The largest land animal alive today, the bush elephant, weighs no more than 10.4 metric tons (11.5 short tons). [ 31 ] Among the smallest sauropods were the primitive Ohmdenosaurus (4 m, or 13 ft long), the dwarf titanosaur Magyarosaurus (6 m or 20 ft long), and the dwarf brachiosaurid Europasaurus , which was 6.2 meters long as a fully-grown ...
