There is no question whatsoever that this is true. My 2010 review of
the history of sauropod research
http://www.miketaylor.org.uk/dino/pubs/taylor2010/Taylor2010-sauropod-history.pdf
contains a handy table on p376 showing how mass estimates for the
single individual HMN SII (the same Giraffatitan that Sellers et al.
use in this study) have varied by a factor of 5.75 -- from Colbert's
(1962) 78258 kg down to Russell et al.'s (1980) 13618 kg.
