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).
Rodolfo Aníbal Coria (born in Neuquén June 1, 1959), [1] is an Argentine paleontologist.. He is best known for having directed the field study and co-naming of Argentinosaurus (possibly the world's largest land animal ever) in 1993, and Giganotosaurus (one of the largest known terrestrial carnivores), in 1995 among other landmark South American dinosaurs, including Mapusaurus, Aucasaurus ...
The titanosaurian sauropod Argentinosaurus huinculensis, one of the largest known land animals, is named after the formation. [2] Another noteworthy Huincul dinosaur is the carcharodontosaurid theropod Mapusaurus roseae , which is regarded as one of the largest known terrestrial predators .
Most of the largest herbivorous specimens on record were discovered in the 1970s or later, and include the massive Argentinosaurus, which may have weighed 80 000 to 100 000 kilograms (88 to 110 short tons) and reached lengths of 30 to 40 meters (98 to 131 ft); some of the longest were the 33.5-meter (110 ft) long Diplodocus hallorum [142 ...
Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
The heaviest blue whale on record weighed 190 metric tons (190 long tons; 210 short tons), [12] and the heaviest dinosaur known from reasonably good remains, Argentinosaurus, weighed 80 to 100 metric tons (79 to 98 long tons; 88 to 110 short tons), although if the size estimates can be validated, it could still be lighter than Bruhathkayosaurus ...
Scale diagram comparing a human and the longest-known dinosaurs of five major clades An adult male bee hummingbird, the smallest known and the smallest living dinosaur. Size is an important aspect of dinosaur paleontology, of interest to both the general public and professional scientists.
Its femur was roughly 1.9 metres (6.2 ft) long, somewhat smaller than the estimated 2.5 metres (8.2 ft) length of the femur of Argentinosaurus. The forelimb was shorter than the hindlimb, with a humerus 78% the length of the femur, as is typical of titanosaurs but unlike some basal titanosauriforms such as brachiosaurids. As in other ...
