Abstract: Ammonoids ruled the seas for 335Myr and present themselves as an especially suitable model when analyzing biological evolution. This synthetic paper focuses on (1): the phylogenetic place of ammonoids within cephalopods and the choice of an extant reference model; (2): the establishment of phenotypic spaces supplying relevant insights into biological evolution; (3): the concordances and discordances between phylogenetic reconstructions and the fossil record, and (4): the postcrisis recoveries, as models to study large-scale evolution. It appears from these topics that ammonoids can be used as case studies for many themes in Paleontology (biodiversity dynamics, phylogenetics, analysis of the fossil record) that offered and continues to offer a better understanding of evolutionary patterns and processes, especially in the context of large-scale studies.

Résumé: Les ammonoïdes qui perdurent 335Ma constituent un modèle de choix dans l’analyse du fait évolutif. Cet article de synthèse se propose d’aborder (1) : leur place phylogénétique au sein des céphalopodes et le choix d’un modèle actuel de référence ; (2) : la construction d’espaces phénotypiques qui offrent un angle d’étude pertinent de l’évolution biologique ; (3) : les concordances et discordances entre reconstruction phylogénétique et registre fossile et (4) : les reconquêtes postcrises, modèles d’étude de l’évolution à grande échelle. Il ressort que les ammonoïdes peuvent servir d’appui à de nombreuses thématiques paléontologiques (dynamique de la biodiversité, analyse phylogénétique, analyse du registre fossile) qui permettent et qui permettront encore de mieux cerner l’évolution biologique, notamment dans un contexte d’étude à grande échelle.
