Comment on Apatosaurus Size by SameerPrehistorica

I remember like 50 tonnes mentioned for that specimen which is a sub adult, then the next thing i know is that the weight for this animal increased upto 80 tonnes which should be the adult's weight. So,40 or 50 to 80 tonnes. Obviously the full grown male will easily surpass 50 tonnes. The other Apatosaurus species are in the range of 30 to 50 tonnes.
