Table 1. Approximate rotational angles of three heteromorph ammonite designs. The dimensions of the original shells of three different designs are compared with the estimated rotational angles based on our model. All lengths to the nearest 5 mm, angles to the nearest 5°.
| Shell Type | Aspinocone | Ancylcone | Hamiticone |
| Genus | Tropaeum | Ancycloceras | Hamites |
| Whorl height | 60 cm | 40 cm | 30 cm |
| Whorl width | 50 mm | 20 mm | 10 mm |
| Rotational angle | 40º | 50º | 100º |
