Turricula (gastropod)

Turricula is a genus of sea snails, marine gastropod mollusks in the family Clavatulidae.

[1] Clavatulidae was raised, based on cladistic analysis, from subfamily to the family level by Rosenberg in 1998.

It remained regarded as a subfamily of Turridae by several malacologists (Kantor, Sysoev).

[1] until a new publication in 2011[2] This genus is known in the fossil records from the Cretaceous to the Quaternary (age range: from 70.6 to 0.0 million years ago).

The anal sinus is situated in the infrasutural depression above the peripheral carina.
