title: Liste de genres d'ammonites
text: # Liste de genres d'ammonites
  
  Cette liste d’« ammonites » est une première tentative pour lister tous les genres de la sous-classe des Ammonoidea (hors termes vernaculaires).
  
  Cette liste comprend les genres communément acceptés (en italique), mais aussi les genres désormais considérés comme invalidés, douteux, n'ayant plus cours ou n’ayant pas encore été officiellement publié (désignations « nomen nudum »), dans la sous-classe des ammonoïdés.
  
  Cette liste contenait 2 460 noms en avril 2015 (2 187 en décembre 2007).
  
  ## Conventions de nommage et terminologie
  
  Ce sont celles du Code international de la Nomenclature zoologique (ICZN)
  
  ## Fiabilité de cette liste
  
  Une majorité des noms de genre de cette liste provient du recueil publié par Jack Sepkoski en 2002 sur les genres de fossiles marins. Des genres d’ammonite découverts après l'époque de cette publication peuvent donc manquer.
  
  D'autre part, en raison du grand nombre de genres d’ammonites, parce qu'ils sont mal connus, et parce que cette liste ne veut pas mentionner les noms invalides, les synonymes et les noms douteux, cet article sous-estime nécessairement le nombre réel de genres décrits et plus encore ceux présents dans les collections privées ou publiques.
  
  Les lecteurs et contributeurs spécialistes sont invités à compléter cette liste (en précisant leurs sources).
