Small ichthyosaur bone block

This surf-worn cobble shows three ichthyosaur vertebrae, and six rib pieces, three on either side, with one longer one right at the surface. Insets at right show other views with other fossils showing. I think the four objects in the top-right panel are ammonite outer whorl cross-sections, possibly Dactylioceras gracile. I thought they were paddle digits initially, but after preparation they show scalloped margins. The bottom-right view shows clear ammonite cross-sections and another object similar to those in the top-right. Cobble was polished with sandpaper.
