Here are two photos of what I infer to be C8 of OMNH 53062, the holotype of Sauroposeidon . The top one was taken by Mike during our visit to the OMNH in 2007. If you’re a regular you may recognize it from several older posts: 1, 2, 3. The bottom one was taken by Mike Callaghan, the former museum photographer at the OMNH, sometime in 1999 or 2000.
