This one’s not about the morphology of the vertebrae, but rather their cumulative effect. The subject is the mounted Brachiosaurus outside the Field Museum in Chicago. The picture was taken in July 2005 by me or by Mike; we had two Nikon Coolpix cameras going and just pooled the photos. We’ll get you some sacrals, caudals, and non-brachiosaurids one of these days. We swear.
