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 ...
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 ...
Millions of years ago, the dinosaurs that dominated the planet came in all shapes and sizes. The tyrannosaurus was a nearly 40-foot-long apex predator.Shuvuuia, on the other side of the size scale ...
One of the traits that helped make the dinosaurs such an evolutionary success story - thriving for 165 million years - was their fast growth rate, from massive meat-eaters like Tyrannosaurus to ...
The remains have been lost, but the sacrum drawing remains. It suggests a sacrum of almost 1.3 m (4.3 ft) long, [439] making it the largest dinosaur sacrum discovered so far, except those of Argentinosaurus and Apatosaurus. [440] In 2010, the femur of a large sauropod was discovered in France. The femur suggests an animal that grew to immense ...
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.
