When used, the developmental information is reduced to one character for two or three different ontogenetic stages. This paper aims to discuss the use of ontogenetic information for phylogeny reconstruction using cladistics. The objective of this work is to introduce ontogenetic character variations between taxa into the coding scheme. The proposed method is based on (1) the recognition of ontogenetic stages in ontogenetic trajectories, (2) finding regressions which represent well each stage, (3) coding the parameters of these regressions into a taxon/character matrix. These regressions are based on traditional growth models. This method is employed to reconstruct phylogenetic relationships within the ammonite family Amaltheidae. Previous studies have shown the importance of ontogeny for understanding the evolution of this family. 33 characters are used for 25 species. Based on the same data set, a second analysis has been performed only on the adult stage. Comparisons of retention index, bootstrap support and stratigraphic congruence between the two analyses show that the inclusion of ontogeny in this method yields better phylogenetic reconstruction. Independence tests on every pair of character coding shows that ontogenetic variations of the different characters have to be coded separately. } }
