I know of no other Patagonian specimens yet described that suggest
bigger animals than _Argentinosaurus_ (although _Antarctosaurus
giganteus_ runs it close). There may well be undescribed material.

Yes, there have been many such limits theorized :-)
Economos 1981 suggested a ludicrously low upper limit of something
like 20 tonnes; this was contradicted pretty emphatically by Hokkanen
1986, whose limit was "between 100 and 1000 tonnes".
