Pubblicato in Sauropod Vertebra Picture of the Week

Thanks to everyone who’s engaged with yesterday’s apparently trivial question: what does it mean for a vertebra to be “horizontal”? I know Matt has plenty of thoughts to share on this, but before he does I want to clear up a couple of things. This is not about life posture First, and I really should have led with this: the present question has nothing to do with life posture.
