This photo an 16th century galleon in the Baltic reminded me that similar crushed fossils sometimes provide more data at a glance than first meets the eye.
Here is the R156 specimen of Dorygnathus about to eat a displaced femur.
And here is how the displaced ‘planks’ (in this case, phalanges) can get put back together using DGS (digital graphic segregation) techniques: colorizing the bones then moving the colors into a reconstruction, checking with PILs. A little intuition and experience also helps.
