        First, somebody please straighten me out on this- 1 ton= 2000 
lbs. 1 long ton=2200 lbs. 1 tonne=1 metric tonne=approx 2200 lbs? Is this 
right? 
        Anyway, my question: what about Collossochelys (aka Geochelys?) 
which is an obscenely big tortoise from India- a couple tons or so, if I 
remember correctly. How does this fit in? What about Megalania? Wasn't it 
about a ton in weight?
