It is probaly either Seismosaurus, Sauroposeidon, or Brachiosaurus but they're all pretty enormous. Brachiosaurus is the size of a 5 story building!
Edit: It depends on what you mean by ''Biggest''. Usually that means the most massive or heaviest. The biggest group of herbivorous dinosaurs where the sauropods (the ''long necks'').
Every dinosaur weight or mass you have ever heard is an estimate. Estimates are difficult when you only have the bones because of the uncertainties of unknown soft tissue. Also the largest known dinosaurs arrn't very complete which makes estimating even harder. In short there is no straight answer.
Take Brachiosaurus brancai (some call it Giraffatitan brancai ). It has been estimated as low as 15 tons and as high as 80 tons using different estimates.
Those two estimates are extreme and are generally thought to be wrong. Most estimates these days put it in the 25-30 ton range.
Argentinosaurus is undoubtingly a massive animal but it isn't fully known. There are a lot of uncertainties as to its exact proportions. Estimates have ranged from 60 -100 tons.
There are other, even less complete giant dinosaurs which 'might' be bigger.
Here are some other potential candidates to look into:
Amphicoelias, Futalognkosaurus, Puertasaurus, Paralititan, Antarctosaurus, Sauroposeidon, Turiasaurus
There are also some giant hadrosaurs (duck bill dinosaurs) that grew very large. But not as large as sauropods.
The worlds smallest herbivore is a caterpillar.
Well if we see direct at the point i think the largest herbivores dinosaur is sesimosaurs.
The elephant is the biggest herbivore currently living.
A Giraffe :)
The elephant and the blue whale.
It's herbivore because it eats the leaves and eats passed away pepole
Herbivore
Goat is a herbivore.
Yes. It is a herbivore
herbivore, as it eats grasses.
The Argentinosaurus
No, it's a decomposer.
No, it's a decomposer.
Earth is the biggest.
The biggest animal on earth is the blue whale.
no, the pacific is the biggest on the Earth
It's herbivore because it eats the leaves and eats passed away pepole
Because it is the biggest animal on earth.
Yes Mount Everest is The Biggest Mountain On Earth But The Biggest Mountain in the Universe Is Olypus mons which is'nt on Earth its on Mar's.
The biggest dinosaur overall in history was the Argentinasaurus, a long necked herbivore. But, the biggest carnivore was the Spinosaurus which was recorded to be 45 feet long, but it's biggest length ever recorded was 60 feet long!
The Blue Whale is the biggest animal on Earth.
im pretty sure that the tiger not the lion is the biggest cat on earth
