One of the dinosaurs actually has beaten the blue whale's record- Seismosaurus was 120 feet, while the Blue whale is 120 feet, too. Yet another is Argentinosaurus. It is estimated to have grown up to 145 feet at the maximum. The blue whale's record is 100-120 feet.

Haha..Yes,there are some Dinosaurs which are longer than Blue whale but when we talk about blue whale,it's the size that matters.Seismosaurus doesn't exist.It is called as Diplodocus hallorum and it is not 120 feet.Argentinosaurus is estimated upto 120 feet long or so and there are some longer sauropods too like Supersaurus..so on.But the thing is none of these Sauropods are heavy as Blue whale.Some people use to say it is not possible for a land animal to weigh over 110 tonnes which i don't believe that much.There is only one Sauropod which is like 200 feet long or may be over longer than that and weighs 125 tonnes or so as being a Diplodocid.That Sauropod is called as Amphicoelias fragillimus but it is only known from one enormous fragmented vertebra.So no use in talking about how much it weighed.There are unknown big tracks of Sauropod found too.There is another Sauropod called as Bruhathkayosaurus weighing 220 tonnes which is believed to be the largest Dinosaur ever lived discovered in the country where i live.The joke is..The authors first thought it was a monstrous Theropod and later described it as a Sauropod.The fossil included hip bones,femur,tibia,a forearm and a tail bone(part of a vertebra). They lost those bones and the paper they had as it seems.Who knows what they are doing.Seems like what they discovered was some pieces of wood.Lol.Anyway,i believe there could be a Sauropod which would have weighed more than Blue whale or at least rival it.
