Figure 2

Results of morphological analysis. Points from the same individual are connected with a line. Arrows indicate the direction of growth. (A) PCA plot graph for sutural morphology. (B) PCA plot graph for conch geometry (cross-sectional morphology). (C) PC1 plotted against conch diameter for sutural morphology. (D) PC2 plotted against conch diameter for sutural morphology. (E) PC1 plotted against conch diameter for conch geometry. (F) PC2 plotted against conch diameter for conch geometry. (G) Septal spacing (septal rotational angle) plotted against chamber number. (H) Septal spacing (septal rotational angle) plotted against conch diameter (mm).
