i think that the biggest dinosaur is sauroposeidon

The biggest is amphicoelias fragillimus the second biggset is Bruhathkayosaurus and the third is Sauroposeidon

cool good to know :D

okay! so..... agintanosaurus (i know i speld it wrong .igen.) is not the biggest? okay....

how big is amphicoelias fragillimus?

Estimates place Amphicoelias fragillimus anywhere from 130 feet to 190 feet. The weight is guessed to be close to that of a blue whale.

thanks for the good info

:D :D :D :D :D

i think the biggest dino is sauroposiedon

If Wikipedia is to be believed, Argentinosaurus was the most massive, at 80,000-100,000 kilos, and Supersaurus is the longest, with an adult length of 33-34 meters. Sauroposeidon is possibly the tallest known, reaching to about 6-7 meters at the shoulder and capable of raising its head to 17 meters above ground level.

Bear in mind that this is in reference to dinosaurs that are reasonably well known. Extrapolation from the dimensions of the (now lost) partial vertebra of Amphicoelias indicates an adult animal potentially 40-60 meters long and tipping the scales at 122,000 kilograms or so. There is also some extremely fragmentary evidence suggesting that Bruhathkayosaurus may have attained a length of 28-34 meters and a mass of up to 139,000 kilograms or so; remember that these estimations are highly speculative, due to the highly incomplete nature of the specimens.

But all of this is easily found on the Interwebs. In short: :google:
