Fig. 5 in Morphological disparity of early ammonoids: A geometric morphometric approach to investigate conch geometry

Fig. 5. Diagrams showing the morphospace occupation observed for the three stages constituting the Early and Middle Devonian (A–C), with level contours and density curves; based on the analysis of the whorl profiles. The grey dots correspond to the data recorded for the entire studied time interval (Early and Middle Devonian); the black dots refer to the data recorded for each of the studied stage (respectively, Emsian, Eifelian, and Givetian). The colours refer to the density of the data in the morphospace; the red-yellowwhite gradient indicates the decreasing density of occupied areas. Compare also with density curves (in grey) above and to the right of the diagrams.
