# Liste des genres de gastéropodes marins

Cette liste des genres de gastéropodes marins est une tentative de regrouper tous les genres connus d'escargots de mer ou de mollusques gastéropodes marins qui ont été retrouvés dans les archives sur les fossiles. Presque tous ces genres avaient des coquilles car il est relativement rare pour les gastéropodes sans coquille (limace de mer) de laisser des traces reconnaissables.
Il faut souligner que cette liste ne représente qu'une infime partie du nombre de genres qui ont dû effectivement exister au cours des ères passées. Les connaissances sur ces fossiles sont extrêmement inégales et ne constituent qu'un témoignage très incomplet de la vie sur terre dans les précédentes ères géologiques.
De nombreux genres de cette liste existent encore. Si, dans la version actuelle de cette liste, ils sont marqués par erreur comme disparus, avec une "†" à côté du nom, cela devrait progressivement être corrigé au cours du temps.
La liste comprend les noms scientifiques de genres de la classe des gastéropodes en excluant les noms vernaculaires. Elle donne tous les noms de genres communément acceptés, mais elle comprend également des genres qui sont désormais considérés comme non valides ou douteux (nomina dubia) et les noms qui n'ont pas été officiellement publiés (nomina nuda) ainsi que des synonymes homotypiques de noms corrects.
La liste comprend aussi quelques genres qui ont d'abord été décrits comme des gastéropodes, mais qui ne sont plus considérés comme en faisant partie et qui, dans de nombreux cas, ne sont même plus considérés comme des mollusques.
Les genres sont énumérés ici par ordre alphabétique, sans aucun essai de les regrouper en famille ou autre taxon plus élevé.
