Data from: Patterns of intraspecific variation through ontogeny–a case study of the Cretaceous nautilid Eutrephoceras dekayi and modern Nautilus pompilius

Amane Tajika, Neil Landman, Naoki Morimoto, Kenji Ikuno & Tom Linn
The magnitude and ontogenetic patterns of intraspecific variation can provide important insights into the evolution and development of organisms. Understanding the intraspecific variation of organisms is a key to correctly pursuing studies in major fields of palaeontology. However, intraspecific variation has been largely overlooked in ectocochleate cephalopods, particularly nautilids. Furthermore, little is known regarding the evolutionary pattern. Here, we present morphological data for the Cretaceous nautilid Eutrephoceras dekayi (Morton, 1834) and the modern nautilid Nautilus...
