Not the internet in this case. The scientific literature.
Mamenchisaurs have been described as being slender, with masses comparable to
diplodocids of similar body length. As you said, your new super-mamenchisaur
"Looks pretty much like other mamenchisaurs". However, the idea of a
super-heavy mamenchisaur contradicts everything that's been said before about
mamenchisaurs. I think I can be forgiven for querying how a mamenchisaur could
weigh 75 tonnes (nearly 1.4 times more than _Argentinosaurus_). My skepticism
was not unwarranted; one might even consider it healthy. I do, and I make no
apologies for it. As I'm forever telling my students: "Show your working".
And yes Jaime, I'm aware that GSP's measurement is based on a single apparent
specimen of _M. sinocanadorum_. However, the only way to arrive at a mass of
75 tonnes is for this specimen to have proportions that depart radically from
the slender, diplodocid-like proportions described for other mamenchisaurs (see
Anyway, there's been enough chest-beating in this thread, so I'll leave it
