I don't know: how massive are trees?

Seriously, the hypothesis that this is no more than petrified wood has not been 
falsified yet to my satisfaction. A detailed
photograph, and even better a micrograph, would go a long way towards 
demonstrating that this was something closer to
_Argentinosaurus_ than to _Araucaria_.
