Giant estimates for Breviparopus are only possible based on comparisons with Giraffatitan assuming barely any skin covering and wrongly comparing length to width. The tracks are only 90cm wide, those of Giraffatitan are 68- 73cm for the bone alone, add an skin hugging extra 5% for the soft tissue or a more realistic 20% and it ends up to 71-88cm. At best Breviparopus was 29m long but it most likely was closer to 23m, assuming equal proportions to Giraffatitan.

OK, first, I would like to see this source that gives a size of 68-73 cm. for the footprints of Giraffatitan (and it's only the bone).
Second, I don't think skin tissue can enlarge Giraffatitan's footprints by 20%. 5% sounds more realistic.

Breviparopus' tracks were 90 cm wide indeed, but the edges of the footprints are collapsed so they could have been a little bigger.

And it’s not just skin tissue. Are the soles of your feets only skin that directly overlays the bones?

Does skin and tissue under it make my foot longer by 20%?

This is not about length.
Does it add 10% to its width on either side? Yes, possibly.

sauroposidon is most likely the tallest

Seeing as there still is debate how high exactly sauropods held their necks, this question probably is impossible to answer aside from "one of the big sauropods"

No exactly, even if we are unsure of neck position, shoulder height is still an option when gauging what the tallest Dinosaur was.

When the poll says "titanosaurus was discovered in Argentina this year" does it mean Dreadnoughtus or that new titanosaur that is yet unnamed?

Which new titanosaur do you mean?

https://en.wikipedia.org/wiki/Unnamed_Patagonian_titanosaur_%282014%29

it needs at least 5 words
By the way, is there any thread where we can propose names for that titanosaur, until it is actually given an official name?
