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 oldest known unequivocal sauropod dinosaurs are known from ... Fossils from perhaps the largest dinosaur ever found were discovered in 2012 in the Neuquén ...
The largest of non-sauropod sauropodomorphs was the unnamed 16 metres (52 ft) long 10 tonnes (22,000 lb) unnamed Elliot giant. [27] Another large sauropodomorph was Euskelosaurus . It reached 12.2 m (40 ft) in length and 2 t (2.2 short tons) in weight. [ 32 ]
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.
Titanosauria have the largest range of body size of any sauropod clade, and includes both the largest known sauropods and some of the smallest. [25] One of the largest titanosaurs, Patagotitan, had a body mass estimated to be 69 tonnes (76 tons), whereas one of the smallest, Magyarosaurus, had a body mass of approximately 900 kilograms (2,000 lb).
Maraapunisaurus is a genus of sauropod dinosaur from the Late Jurassic Morrison Formation of western North America. Originally named Amphicoelias fragillimus, it has sometimes been estimated to be the largest dinosaur specimen ever discovered.
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. It is one of the largest ...
Size compared with a human. Turiasaurus is believed to be the largest dinosaur ever found in Europe, and is among the largest dinosaurs known. It was originally estimated at over 30 metres (98 ft), possibly around 36–39 metres (118–128 ft) in length and with a weight of 40–48 t (44–53 short tons). [1]
