While I was thinking about Diplodocus atlas ribs, I was reminded of the ribs on the atlas of a diplodocine skull-and-three-cervicals exhibit that Matt and I saw at MOAL(*) back in the heady days of the Sauropocalypse. And that reminded me that I have other pairs of photos from the MOAL visit, which I took with the intention of making anaglyphs. like the one I did of the diplodocine.
