FIGURE 2 in Outline analysis as a new method for investigating development in fossil crabs
FIGURE 2. Scheme of the methodology. Step 1 (s1): Half of the shield outline is reconstructed from source image in dorsal view. Step 2 (s2): The half of the shield is then duplicated and mirrored in anterior-posterior axis and stitched together to form an entire symmetric shield. Step 3 (s3): The shield is registered in R using the Momocs package with 1493 +/- 259 coordinates for the Carcinus data set and 3053 +/- 1736 coordinates for the Liocarcinus data set.
