Pubblicato in Sauropod Vertebra Picture of the Week

As promised, some thoughts on the various new brachiosaur mass estimates in recent papers and blog-posts. Back in 2008, when I did the GDI of Giraffatitan and Brachiosaurus for my 2009 paper on those genera, I came out with estimates of 28688 and 23337 kg respectively. At the time I said to Matt that I was suspicious of those numbers because they seemed too low.
