The list is actually not too bad. Most of the higher estimates are somewhat too high, but not insanely so. I don't get any titanosaurs exceeding 60 tonnes, with the new mounted specimen being about the same size as Argentinosaurus or maybe a tad bigger. I've been supplied accurate measurements for Futalognkosuaurs which turns out to be the same size as way overblown Dreadnaughtus which was around 25 tonnes (https://figshare.com/articles/Not_so_gigantic_after_all_Response_to_Lacovara_et_al_/1264019). There are apatosaur specimens that indicate huge individuals, those from OK that Wedel mentions, plus that alleged super gigantic dorsal vertebra Cope illustrated that might be from an apatosaur -- there is no particular reason to refer any of these specifically to A. ajax which may be limited to the material in the original quarry, the mounted Japanese juvenile Apato is probably a different species. Xu Xing tells me there are a couple of supersized cervicals from the same formation as M. sinocanadorum that suggest the later got real enormous (an entire skeleton has been modeled from that, it's on Google).
Fact is that the largest land animal known from really good skeletal remains is still good ol Giraffatitan branci, with the mounted skeleton being around 30 tonnes (it is possible that the back half of that is not the same taxon, but they are all similar proportioned brachiosaurs).
My revised mass table tied to the 2nd edition of the field guide is placed at http://press.princeton.edu/titles/10851.html.

Subject: [dinosaur] The table of largest sauropods
I would like to ask, if the wikipedia table of largest/heaviest sauropods is currently valid and up-to-date (it doesn´t seem so)? Could it look like this perhaps? Thank you, Tom
1. Argentinosaurus huinculensis - 70 - 96 tonnes
2. Puertasaurus reuili - about the same
3. Unnamed Patagonian titanosaur - around 77 tonnes
4. "Antarctosaurus" giganteus - 40 - 80 tonnes
5. Notocolossus gonzalezparejasi - 45 - 75 tonnes
6. Apatosaurus ajax - 40 - 75 tonnes
7. Futalognkosaurus dukei - 50 - 70 tonnes
8. Mamenchisaurus sinocanadorum - 50 - 65 tonnes
9. Sauroposeidon proteles - 50 - 60 tonnes
10. Dreadnoughtus schrani - 40 - 60 tonnes
