im stuck what was the largest dinosaur please help!?

Answer 1

The answer is.....

We can't be sure. First you must understand that complete skeletons of dinosaurs are almost never found, and most dinosaur genera are only known from a few bones and teeth.
There ARE many kinds of dinosaur that are certainly cantidates for being the largest. I'll list a few of them.

Argentinosaurus
Supersaurus
Ultrasauros
Seismosaurus
Sauroposeidon

All of these belong to the group of dinosaurs called sauropods.
Sauropods were the huge, long-necked, long-tailed, four-legged dinosaurs that everybody knows about. They lived in the Jurassic and Cretaceous periods, from about 180-65 million years ago.
Most of the sauropods are only known from scanty fossil material, so we don't have any complete skeletons to compare. Thus, for the most part, we can't really really be sure.


HOWEVER, there is one dinosaur, that, if the stories are true, would be by far the biggest.
The story goes like this - in 1878, paleontologist Edward Drinker Cope found something truly remarkable. It was a dorsal vertebra (backbone) of a sauropod dinosaur. The remarkable thing about it was its size - it was over six feet tall!
Dr. Cope saw that this was far larger than the vertebrae of any other sauropod, so he gave it a new name (perhaps rather dubiously, though, because it was only known from one fossil) - Amphicoelias fragilimus. If this dinosaur, Amphicoelias, had proportions similar to other sauropod dinosaurs, then this fossil demonstrates that Amphicoelias could have been up to 200 feet long and could have weighed up to 150 tons!
The problem is that the fossil was lost somewhere when it was being shipped back to the East Coast via railroad. All we have now to show for it are some drawings that Cope made.

We can be sure, though, that if more fossils of the same size are ever found, then Amphicoelias will claim the title of largest dinosaur ever found.

Answer 2

The LONGEST known dinosaur was a plant-eating sauropod (long-necked, long-tailed, walked on all four feet) called Seismosaurus. Seismosaurus was between 120 and 150 feet long, weighed about 80 tons, and is known from fossils found in New Mexico. However, the recent discoveries of enormous vertebrae and sacrum bones from Argentinosaurus (a close relative of the Brachiosaurus) have caused some paleontologists to believe this could be the HEAVIEST dinosaur.
We may never know exactly which dinosaur was the biggest, but we can be fairly sure it was a sauropod of some kind!

Answer 3

You can't miss the world's largest dinosaur, a towering Tyrannosaurus Rex That stand 26. 2 meters(86 ft.) tall and overlooks the Drumheller Valley. The t-rex os also the largest meat eating dinausaur.......

Answer 4

The largest and the most fearful dinosaurs that ever walked the face of earth was Tyrannosaurus rex.It was 15 meters long and stood 6 meters high.its head was disproprotionately great with large jaws armed with dagger-like teeth 15cm long.
But Sauropoda like Apatosaurus,Diploducus,Branchiosaurus etc are more than 25 meters long and weighing over 50 tons.they had long necks and tails,small head with small brain and weak jaws.

Answer 5

Puertasaurus is one of the biggest dinosaurs ever found

Answer 6

Sauroposeidon

Answer 7

Seismosaurus

Answer 8

Bruhathkayosaurus, thats my guess. That is real one though, as fake as it sounds.
