the biggest one

[B.Dol@skn.sc.philips.com]

Hello list-friends,

I know this question has been asked before, but my company has had a 
systemcrash (Philips; let's make things better...) and I lost a 
rather large part of my saved mails.
What was the name of that largest sauropod found? If I remember 
correctly, the only bone which was found (?a vertebra of 2.5m tall? is 
missing at this moment. I had been searching for half a year for that name
and now it's gone again. I hope someone can help me out.
