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).
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 ...
The specimens found were remarkably complete, significantly more so than previous titanosaurs. It since been suggested that Patagotitan was not necessarily larger than Argentinosaurus and Puertasaurus. [30] In 2019, Patagotitan was estimated to have been 31 metres (102 ft) long and about 55 tonnes (121,000 lb). [31]
If true, it would make Bruhathkayosaurus the single largest terrestrial animal to have walked the earth and would have rivalled the largest blue whale recorded. [ 412 ] BYU 9024, a massive cervical vertebra found in Utah , [ 413 ] may belong to a Barosaurus lentus [ 414 ] [ 415 ] or Supersaurus vivianae [ 416 ] of a huge size, possibly 45–48 ...
Size of a few specimens compared to a human. Mapusaurus was a large theropod, but slightly smaller in size than its close relative Giganotosaurus, with the largest specimen measuring around 10.2–12.2 metres (33–40 ft) long and weighing up to 3–6 metric tons (3.3–6.6 short tons).
Ancient giant stromatolites used to be widespread in Earth’s Precambrian era, which encompasses the early time span of around 4.6 billion to 541 million years ago, but now they are sparsely ...
This would make the titanosaur larger than Argentinosaurus, another species of titanosaur. A ridge on the back of one of the vertebrae, and a few other features allowed the team to identify the titanosaur as a new species. Volcanic ash around the bones dated them to 101.6 million years old.
