Be that as it may, I was using the available literature as a guide. Here,
mamenchisaurs have been explicitly described as very slender sauropods. For
example, in the original description of _Mamenchisaurus sinocanadorum_,
Russell and Zheng (1993) write:
"_Mamnechisaurus_ was probably not as ponderously built as were
_Brachiosaurus_ and _Apatosaurus_... because so much of its length
consisted of an extremely long and light neck.... The proportions
of the distal portion of the femoral shaft associated with the type
skeleton of _M. hochuanensis_... are consistent with a body weight
similar to that of _Diplodocus_."
Now, I'm not denying that the mounted mamenchisaur skeleton you're referring to
is "one big pappa". But to suggest that it was an exceptionally heavily built
sauropod that could have weighed 75 tonnes in life goes against everything that
has been said previously about mamenchisaurs. Again, I'm not saying you're
wrong, but it's an extraordinary claim. At the very least, this "big pappa"
sounds very un-mamenchisaur-like.
