What is the heavest dinosaur?

Answer 1

The biggest dinosaur was infact the biggest animal ever!

Its called the LIOPLUERODON. It lived in the sea and actually ate anything even sharks!One flipper is 5 metres long and from head to tail it was 25 metres long. It weighed close to 150 tonnes! If washed up on land its lungs would be suffocated by its own weight!

Answer 2

The heaviest dinosaur known from good skeletons is brachiosauros between 30,000 and 60,000 kilograms (70,000 and 130,000 lb

Edit: 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

Answer 3

It is very hard estimate the heaviest dinosaur. Many dinosaurs species are only known from a few fossil fragments. Complete dinosaurs are very rare indeed.

It is almost certain however that the heaviest was of the Sauropoda class of dinosaurs. Estimates of dinosaur weights suggest that the heaviest was either a Titanosaur or Diplodocid or possibly a Brachiosauridae. * Bruhathkayosaurus (Titanosaur) - estimates range from 175-200 tonnes * Seismosaurus (Diplodocid) - about 100 tonnes * Argentinasaurus (Titanosaur) - estimates between 80-100 tonnes * Brachiosaurus (Brachiosaurisae) - estimates of about 80 tonnes * Parilititan (Titanosaur) - estimated to be 60-80 tonnes * Sauroposeidon (Brachiosauridae) - estimates of 50-60 tonnes * Supersaurus (Diplodocid) - 40-50 tonnes

Answer 4

Argentinosaurus was the heaviest dinosaur, weighing around 100 tons

Answer 5

The largest animal to ever live, 115 ft long, 67 ft tall (?), Argintinosaurus, 11 tons

Answer 6

The heviest dinosaur was argentinosaurus.It was thaught to way about 80-100 tonnes

Answer 7

It is "argentinosaurus," it is also the bigest.

Answer 8

Spinosaurus.
