Citation: Navisolenia Lecal 1965
Rank: Genus
Navisolenia * ,

Original description: Ce genre est défini par une coque régulièrement allongée en navette, dont les extrémités très étirées sont le résultat d'une diminution des scapholithes en taille et en nombre. Les scapholithes au moment de leur formation ont un fond inorganisé, tandis qu'avec la maturité cellulaire le fond s'organise en une structure définie du type « scalae ».

Translation (JRY - 2019)
This genus is characterised by a shell that is reguarly elongated in a shuttle-shape, the extremities of which are very extended as a result of a diminution of the scapholiths in size and number. The scapholiths at the moment of their formation have a unorganised base, whilst with maturity of the cell the base becomes organised into a definite structure of the ladder type. [NB scalae is the plural of the latin word scala - ladder]
