Robert Melton sent me the following data RE: Loxodonta masses, which I pass on 
to the rest of you:
Gerald L. Wood "Animal Facts and Feats"
Sterling Publishing Co. New York 1978
also lists these:
 
    Dhululamithi       384 cm   ~=  9000 kg ~= 19,800 lbs
    1960vanderByl   383 cm   ~=  8900 kg ~= 19,600 lbs
    1875Alfred         396 cm   ~=  9800 kg ~= 21,600 lbs
    1849Oswell       371 cm   ~=  8100 kg ~= 17,800 lbs
    1839Harris        365 cm   ~=  7800 kg ~= 17,200 lbs

So with this data in hand, a 10-11 t Triceratops becomes more reasonable.
