Giganotosaurus carolinii, Argyrosaurus superbus,Titanoboa cerrejonensis, Irritator challengeri, Purussaurus brasiliensis, Mourasuchus amazonensis, Mapusaurus roseae, Oxalaia quilombensis, Notocolossus gonzalezparejasi, Argentinosaurus huinculensis, Puertasaurus reuili, Antarctosaurus giganteus, Saltasaurus loricatus,  Amargasaurus cazaui , Chubutophis grandis, Gryposuchus croizati, Prionosuchus plummeri, Tyrannotitan chubutensis, Dreadnoughtus schrani, Futalognkosaurus dukei, Notiomastodon platensis, Madtsoia bai, Stupendemys geographicus, Megatherium americanum, Cuvieronius hyodon, Doedicurus clavicaudatus, Arctotherium angustidens, Josephoartigasia monesi, Kelenken guillermoi, Smilodon populator, Phorusrhacos longissimus, Brontornis burmeisteri, Black caiman, Green anaconda, Brazilian tapir, Giant Ant eater, Spectacled bear, Jaguar, Maned wolf, Capybara and Greater rhea.

Flying Animals : Pelagornis sandersi and Argentavis magnificens.

The largest land animal alive today in South America is the Brazilian tapir.


South America is simply packed with giants. The largest species of animals from South America as seen in the image :

Largest amphibian - Prionosuchus plummeri

Largest bear / largest terrestrial mammalian carnivore - Arctotherium angustidens

Largest crocodilian - Purussaurus braasiliensis (It can be a debate when it comes to the largest crocodilian ever. May be purussaurus is the largest

crocodilian.)

Largest feline - Smilodon populator

Largest flying bird - Pelagornis sandersi

Largest rodent - Josephoartigasia monesi

Largest living rodent - Capybara

Largest snake -  Titanoboa cerrejonensis

Largest living snake - Green anaconda

Largest turtle - Stupendemys geographicus

Largest xenarthran - Megatherium americanum

Some of the massive dinosaurs are known from South America. The 'largest dinosaur that ever existed' is something which may never be settled since they are known from very fragmentary materials. Possibly the largest dinosaur might be known in the future. For now, the most famous largest dinosaur is argentinosaurus huinculensis.Then there is the larger puertasaurus reuili.

Scared Sherlock You know what's weird though? I don't see macrauchenia. It was a pretty big animal too, you know.

Tard Idea I can imagine a future descendant of the farm llamas being huge half sauropod and half indricothere-shaped grassland mammals, travelling together in herds eating from big trees. Llama jump  That idea I came up with was influenced by speculative evolution. You should look it up. Dougal Dixon's "After Man: A Zoology of the Future" and the 2002 documentary mini series, "The Future is Wild" come to mind.

It's Chubut, Toast is not a real name but a misinterpretation of the exhibit (it was supposed to be 'Toast the Titanosaur' as in 'let's toast the titanosaur'). It's a common one, don't worry.

I know Toast isn't the real name, but I kinda like it more them Chubut Moster.
Hoping it will be described soon, it really needs a real name. :D

Oh another one is the Rio La Plata bones, which Nima Sassani estimated to belong to a 70+ tonne sauropod. This chart could be even more grandiose.

I wonder what was going on there. And undoubtedly there's more waiting to be discovered.

Of course, there are many others to be discovered and there are also many others that will not be discovered, to our sadness :(

I read somewhere, I do not remember now, that Patagonia during the Cretaceous was a flood plain surrounded by coniferous forests in a temperate climate. Perhaps these conditions have favored the development of giant titanosaurus over the time. Although not the only ones, both Morrison sauropods and Alamosaurus evolved in a savannah-like environment, seasonally dry in the middle of the year and humid in the other.

Ah that definitely makes sense. Of course there were other giant sauropods elsewhere, but it must be why Argentina suited them so well. China was good for them as well, North America too.

You could have added Macrauchenia and Toxodon to this image.

The only continent where theropods still ruled as the alpha predator until a mere 2 million years ago. Also I love how Prionosuchus is laying on top of the gharial.

It's amazing how the largest animals of modern day here are only slightly larger than the sauropod's heads!

Two more sauropods are the Chubut Monster (the largest specimen is bigger than Argentinosaurus or Alamosaurus, probably rivalling Puertosaurus) and the Gigante de Rio Negro, which is probably similar in size to Paralititan or Antarctosaurus.

Thank you. Come on, any giant theropod would look bigger for us but not for some gigantic sauropods.

I like how the largest living animal dwarfs beneath predators, that could eat it in a single bite.
