| Résumé : | Raup's model of shell growth, now in standard use, is operational only for strictly conispiral shells. The pertinence of evolutionary interpretations of the distribution of existing shells in the morphospace defined by Raup's parameters is questioned. A simple, more general model accounts for the non-isometric growth of many shells. Some aspects of the distribution of existing shells in the morphospace derived from the new model are discussed. |
