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.
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).
The remains have been lost, but the sacrum drawing remains. It suggests a sacrum of almost 1.3 m (4.3 ft) long, [432] making it the largest dinosaur sacrum discovered so far, except those of Argentinosaurus and Apatosaurus. [433] In 2010, the femur of a large sauropod was discovered in France. The femur suggests an animal that grew to immense ...
Patagotitan is a genus of titanosaurian sauropod dinosaur from the Cerro Barcino Formation in Chubut Province, Patagonia, Argentina. The genus contains a single species known from at least six young adult individuals, Patagotitan mayorum , which was first announced in 2014 and then named in 2017 by José Carballido and colleagues.
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.
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.
“Apex” is the latest dinosaur fossil to be bought by Mr Griffin. In 2018, he gave $16.5m to the Field Museum in Chicago to fund the display of the biggest dinosaur ever discovered, a titanosaur.
