Quentin Wackenheim

Bonjour,

Avez-vous un peu plus d'éléments concernant sur le contexte sédimentaire, son âge et éventuellement la faune associée ?

Je ne suis pas certains qu'il s'agisse d'un taxon holocène.

Mon premier avis est de pencher vers le genre Melanopsis qui un gastéropode d'eau douce.

Bien cdt

Georges Truc

Oui je suis assez d'accord, mais ce gastéropode s'éloigne de la morphologie habituelle du genre Melanopsis ; il est très turriculé, très costulé ; si le contexte est bien holocène, il s'agirait de la plus vraisemblable attribution.

cordialement
