Randomness and Complexity
Fig. 11.1 An ammonite (Ptyichites opulentus Mojsisovich), showing the complex sutures. Figure 5
from Plate 44 in E. Haeckel, Kunstformen der Natur (1. Sammlung). Leipzig: Verlag des Bibli-
ographischen Instituts (1904). A collection of ammonoid fossils showing the increase and decrease
of suture complexity can be viewed at the Musée cantonal de zoologie, Palais de Rumine, Lausanne
