see text Cuphosolenus is a genus of extinct small to medium-sized sea snails, marine gastropod mollusks in the family Aporrhaidae and the superfamily Stromboidea, known from the Jurassic[1] and lower Cretaceous[2] periods.

[5] In 1891, Piette accepted Fischer’s use of Cyphosolenus in the text of Paléontologie Française ou Description des Fossiles de la France, etc., Vol.

[8] The genus includes Aporrhaidae shells with three long, thin finger-like extensions from the aperture and an extended, curved siphonal canal.

The original description described the shell as having (translation from the French), "a semi-palmate lip, three digits, the posterior one of which is weakly attached to the spire, inner lip of columella thick, and siphonal canal bent or curved at the end".

[9] Cuphosolenus has been reported from the Jurassic of France,[10] the Sinai,[11] and questionably from Saudi Arabia,[12] as well as the lower Cretaceous of Texas[13] and Mexico.
