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).
Most of the largest herbivorous specimens on record were discovered in the 1970s or later, and include the massive titanosaur Argentinosaurus huinculensis, which is the largest dinosaur known from uncontroversial and relatively substantial evidence, estimated to have been 70–80 t (77–88 short tons) and 36 m (118 ft) long.
Argentinosaurus: 1993 Huincul Formation (Late Cretaceous, Cenomanian to Turonian) Argentina: May be the largest known dinosaur Argyrosaurus: 1893 Lago Colhué Huapí Formation (Late Cretaceous, Campanian to Maastrichtian) Argentina: Several remains were historically assigned to this genus, but only the holotype can be confidently assigned to it ...
Dinosaurs evolved from more primitive reptiles in the aftermath of Earth's biggest mass-extinction event caused by extreme volcanism at the end of the Permian Period about 252 million years ago.
The bones were similar to other titanosaurs, a group of sauropod dinosaurs with four legs and long necks that were some of the largest dinosaurs that ever lived, and were dated to the correct ...
A nearly complete and intact dinosaur skeleton has been excavated in France. The specimen is a Titanosaur, one of the largest dinosaurs of its time. 70 million-year-old giant dinosaur skeleton ...
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 ...
The UK's biggest ever dinosaur trackway site has been discovered in a quarry in Oxfordshire. About 200 huge footprints, which were made 166 million years ago, criss-cross the limestone floor. They ...
