Sauropod Vertebra Picture of the Week, or SV-POW! for short, was first conceived as a sort of joke response to the excellent Astronomy Picture of the Day. But before long, it became apparent to the three of us that SV-POW! had legs of its own, and that there really was an almost infinite amount of material we could cover. We originally intended each post to be super-short, basically just an image and a caption, but that’s not how it’s turning out.
