No sooner has the ink dried on that one, then this comes out...

Perry SF, Christian A, Breuer T, Pajor N, Codd JR (2008). Implications of an avian-style respiratory system for gigantism in sauropod dinosaurs. Journal of Experimental Zoology [Epub ahead of print] Published Online: 2 Feb 2009

The abstract says

 At 12 ton the predicted body temperature and metabolic rate of a
 growing sauropod would be similar to that of a bird scaled to the
 same body weight, but would increase exponentially as body mass
 increases

What's the upper limit for an "avian-style respiratory system"?
