Limits to dinosaur size?

On the thread "south america: land of giants", someone got a 170-200 tonne Puertasaurus by scaling it from an Argentinosaurus. That would be in the weight range of a blue whale, and beyond the limits of terrestrial creatures.

I don't want that thread to go off-topic, so I'll make this one.

How high is the limit to dinosaur size?

EDIT: I now believe that the limits of terrestrial creatures far exceed the mass of a blue whale

I wish the images and measurements from the 2 meter wide tracks in Thulborn's presentations were recorded!

And I think the 1 to 1.5 ratio between width and length might be a bit extreme, perhaps 1 to 1.2?
I got the 1.5 ratio from the measureent of the large print in the 2012 paper. I do not know how representative this print is.

Theoritically there are no limits in the size of animals. I believe that dinosaurs might have been the largest animals ever. The Broome titanosaur for example might have been over 200 tons in weight. I believe that their limit ranges from 200-1.000 tons. However dinosaurs heavier than a Blue Whale are something difficult to exist.

There ARE limits on size. Factors such as population density, food shortages, predation, disease, stress, age, environmental room, etc. Limit how large a species could hypothetically get.
