Supplementary Figure 1. Distortion generated by the sliding process on the shape of the ribs of Ptychoma, represented with different numbers of coordinates. (A) Original curve (1000 coordinates) representing the most complex ribbing pattern in our sample. (B) Curve transformed to optimum number of coordinates (416) before sliding. (C) Curve transformed to 416 coordinates after sliding. (D) Curve transformed to 300 coordinates after sliding. (E) Curve transformed to 100 coordinates after sliding. (F) Curve transformed to 30 coordinates after sliding. For sliding, the first and last coordinates are treated as fixed landmarks.
