Argentinosaurus is most certainly bigger but it's not very complete. Based on the size of it's large bones it's certainly one of the most massive land animals ever to roam the Earth. Argentinosaurus is a titanosaur sauropod. Because of it's incompletness it's exact length and mass are impossible to know right now. It's mainly known from dorsal vertebra (back bones). The neck and tail are completely unknown and these vary a lot between different sauropods. Length estimates have ranged from 26 to nearly 40m long. Mass estimates have ranged from about 50-100 tons!
Seismosaurus is a diplodocid sauropod was one of the longest dinosaurs. (Currently many paleontologists think Seismosaurus may just be a large specimen of Diplodocus.) It's estimated at 30m long, but a large poportion of this is neck and tail. (Diplodocids have incredibly long tails.) Weight estimates are about 30 tons.

∙ 11y agoAn early reconstruction by Gregory. S. Paul estimated Argentinosaurus at between 30--35 metres (98--115 ft) in length and with a weight of up to 80--100 tonnes (88--110 short tons).

∙ 10y agoThe biggest dinosaur has probably not been discovered, but there are already candidates to outface Argentinosaurus. Part of the problem is that there's no single meaning of "biggest" (Heaviest? Longest? Longest not counting the tail? Tallest on four feet? Highest at the whithers?); another is that rarely are ALL the parts accounted for, so there's a lot of guesswork. For example, "Ultrasaurus" is known only from a thighbone. It's huge, and if the rest of the creature is in proportion... Ah, but is it?

∙ 14y agoIt depends if you call heavy big no but if you call long big yes.

Wiki User
∙ 13y agoIt weighed up to a 100 tons and was like 40 to 40 meters long. That's about a 100 to 150 feet

Isn't the argentinosaurus bigger than the blue whale?
Although Argentinosaurus is twice as long as the blue whale, it only weighs half as much. that's wrong dude, Argentinosaurus was about 30-35 m long and weight 80-100 tonns, the blue whale is also around 30 m some have reach more and they weigh about 170-190 tonns so Argentinosaurus is NOT twice as long Actually both of you are wrong. Argentinosaurus weighs around 73 tons based on recent estimates, while 190 tons is nowhere near average; closer to 120-150 tons. Also Argentinosaurus is not the largest dinosaur; that title probably goes to Amphicoelias fragillimus at 122.4 tons. Even ignoring Amphicoelias, Argentinosaurus still probably does not weigh as much as the 80-85 ton Puertasaurus, though that is a matter of debate.
