You may be right. But how does an animal like _Mamenchisaurus_, in which the
neck makes up at least half the total body length, and the torso less than a
quarter, come to weigh more than a titanosaur of similar body length?
I don't doubt that _M. sinocanadorum_ was big. Very big. But I'm having
trouble comprehending how it could weigh *more* (almost 50% more!) than either
_Argentinosaurus_ or _Futalognkosaurus_. 75 tonnes for _M. sinocanadorum_
versus 50-55 tonnes for the two titanosaurs, when all three animals are
estimated to have measured around 24-25m long.
