They did not recover it as a lognkosaurian but as either a basal titanosaur or a sister taxon of the more derived Epachthosaurus. [28] In 1993, Bonaparte and Coria said the hyposphene-hypantrum articulations were enlarged, as in the related Epachthosaurus, and had additional articular surfaces that extended downwards. Argentinosaurus Was a Type of Dinosaur Known as a Titanosaur . The optimal gait found by the algorithms was close to a pace (forelimb and hind limb on the same side of the body move simultaneously). It is stronger than Giganotosaurus and weaker than Tyrannosaurus Rex. Barosaurus beräknas ha blivit åtminstone 27 meter lång (möjligen betydligt mer) och var länge en av de absolut största kända dinosaurierna men har de senaste 15 åren halkat neråt på den listan när man hittat nya jättar som Puertasaurus, Argentinosaurus, Sauroposeidon m.fl. More than 95 million years ago this animal was part of the Cretaceous period fauna, in the Cenomanian, of present-day South America. This bone was deformed by front-to-back crushing during fossilization. [56], Fossilised pollen indicates a wide variety of plants was present in the Huincul Formation. McIntosh, John S. 2005. By PaleoPastori Watch. Argentinosaurus was a titanosaurian sauropod dinosaur from the Late Cretaceous period. [53] These deposits were laid down during the Upper Cretaceous, either in the middle Cenomanian to early Turonian stages[54] or the early Turonian to late Santonian. It belongs to an animal that was 48 meters (157 ft) long and around 66 tonnes (73 short tons) in weight making it one of the largest known dinosaurs, with a neck length of at least 15 meters (49 ft) acc… [27] Other authors argued most titanosaur genera lacked hyposphene-hypantrum articulations and that the articular structures seen in Epachthosaurus and Argentinosaurus are thickened vertebral laminae (ridges). It was originally reported from the Huincul Group of the Río Limay Formation,[2] which have since become known as the Huincul Formation and the Río Limay Subgroup, the latter of which is a subdivision of the Neuquén Group. (Other titanosaurs, such as Argentinosaurus, may have been even bigger, but are represented by less complete fossil remains.) There is a good possibility that this station is home to the Dinosaur Giganotosaurus and Amargasaurus because of the close range between the stations. Argentinosaurus - Planet Dinosaur - Episode 5 - BBC One. ThoughtCo, Aug. 25, 2020, thoughtco.com/giganotosaurus-vs-argentinosaurus-who-wins-1092420. These gigantic herbivores were about 115 feet long and probably weighed around 73 tons, although some estimates place its weight range around the 85 ton mark. [13][23][7] In 2017, Carballido and colleagues considered Argentinosaurus to be smaller than Patagotitan, since the latter had a greater area enclosed by the neural spine, diapophyses, and parapophyses of its anterior dorsal vertebrae. Argentinosaurus is a genus of giant sauropod dinosaur that lived during the Late Cretaceous period in what is now Argentina. Scientists claim that there are substantial differences between it and Apatosaurus to separate them. The most commonly reproduced quote of mine is this one, originally from Brian’s piece: I think it would be more accurate to say that Argentinosaurus, Puertasaurus and Patagotitan are so similar in size that it is impossible for now to say which one was the largest. Unfortunately, even 25 or 30 tons of combined force isn't enough to dislodge a 100-ton obstacle, and the Giganotosaurus closest to Argentinosaurus' rump has left itself wide open to a supersonic tail flick to the head, rendering it unconscious. Although it was huge, Barosaurus was not very fierce. [8] In 2018, González Riga and colleagues also found it to belong in Lognkosauria, which in turn was found to belong to Lithostrotia. One of the largest sauropods that ever lived, Argentinosaurus grew up to 30 metres (100 ft) in length, making it bigger than even its relatives, such as Alamosaurus and Saltasaurus with weight estimates varying from 70 to 100 tonnes. [38] In 2002, Davide Pisani and colleagues recovered Argentinosaurus as a member of Titanosauria, and again found it to be in a clade with Opisthocoelicaudia and an unnamed taxon, in addition to Lirainosaurus. Argentinosaurus was a large sauropod dinosaur which lived during the Cretaceous period. The first Argentinosaurus bone, which is now thought to be a fibula (calf bone), was discovered in 1987 by farmer Guillermo Heredia on his farm "Las Overas" about 8 km (5 mi) east of Plaza Huincul, in Neuquén Province, Argentina. By Staff Writer Last Updated Mar 30, 2020 5:56:07 AM ET. [50]:206–207, In 2013, Sellers and colleagues used a computer model of the skeleton and muscles of Argentinosaurus to study its speed and gait. Its neck bones were hollow and light, otherwise it wouldn’t have been able to lift its neck up! [5][6] In 1996, Bonaparte referred (assigned) a complete femur (thigh bone) from the same locality to the genus, which was put on exhibit at the Museo Carmen Funes. Size is and has been one of the most fascinating aspects of dinosaur paleontology, to both the general public and professional scientists. Argentinosaurus Feeding - Planet Dinosaur - Episode 5 - BBC One. argentinosaurus huinculensis argentinosaurus huinculensis vs blue whale argentinosaurus huinculensis pronunciation argentinosaurus … [48], The giant size of Argentinosaurus and other sauropods was likely made possible by a combination of factors; these include fast and energy-efficient feeding allowed for by the long neck and lack of mastication, fast growth and fast population recovery due to their many small offspring. Argentinosaurus may have been the largest dinosaur ever, aside fromAmphicoelias,Patagotitan and several other sauropods. Province of Neuquén is very recommended to hunt in the Argentine Province Neuquén. Dimensions of Argentinosaurus was a titanosaurian sauropod dinosaur first discovered by Ms. E. R.
