Description Simple dm/ASarea plot to outline the position of the various studied cross sections. The nine specimens divide into three groups: 1) Forms with a high ASA (*Nautilus*, *Macrocephalites* and in the adult stage *Hammatocyclus*), 2) Forms with a moderate ASA (*Revilloceras* and *Joannites*, *Metalegoceras* in the adult stage) and 3) Forms with low ASA (*Choffatia* and *Sageceras*).

Description Simple ASarea/BMAI plot to outline the position of the various studied cross sections. In the nine highlighted specimens, it is clear to see that for a given ASA there can be a range of BMAIs. The disparity in BMAI increases from the hatchling stage through to the adults. In the subadult/adult stages, some specimens possess relatively small buccal apparatus (*Revilloceras* and *Joannites*) restricting them to smaller food items whereas other specimens were capable of eating larger prey (*Nautilus*, *Sageceras*).

Description Simple WER/ASAI plot to outline the position of the various studied cross sections. The blue lines indicate the relationship between the ASAI and WER for simple geometric apertural shapes, the three lines from the top represent depressed ellipsoids of decreasing intensity, the fourth line a circle and the bottom two lines compressed ellipsoids.
