RE: Largest Dinosaur?

["R. Irmis" <rbi@dana.ucc.nau.edu>]

<<Tsk, tsk.  All these discussions of 'largest dinosaurs' and yet not a
single mention of Seismosaurus?!?  At an estimated 160 ft (?50+ meters) it
is longer than any of the others mentioned to this point.  I will grant
that, as a diplodocid, it probably didn't outweigh Argentinosaurus, and
maybe didn't  even clear 100 tons.  But I just find it odd that Seismosaurus
hadn't received any mention whatsoever.>>

Theres a reason why it hasnt been mentioned.  Gillette misjudged positions
of some of the vertebrae, which had a large impact on the length estimate.
The revised estimates (which I cant remember off the top of my head) are
around the top range that one might expect for Diplodocus, which has lead
some to suggest that Seismosaurus is species of Diplodocus.
