Tubospirina
# Tubospirina

Tubospirina is an extinct genus of fossil sea snails, marine gastropod mollusks in the family Craspedostomatidae. These snails were parasitic-carnivores. They lived in the Silurian Period, Pridoli Age (from 418.7 ± 1.5 to 416 ± 2.8 mya).

## Etymology

The genus name Tubospirina combines the Latin word tubus, meaning "tube" and the genus name Spirina.

## Description

The genus Tubospirina is very similar to the genus Spirina, but it can be distinguished by the dextrally coiled shell with a flatly arched upper side. The shells are large, with a wide aperture and a characteristic ornamentation of rounded costae and interspaces. This new genus has been tentatively placed close to the genus Spirina in the family Craspedostomatidae.

## Species

* Tubospirina tubicina - Previously known as Spirina tubicina Perner, 1903 - recombined as Tubospirina tubicina according to J. Frýda in 1998.

## Distribution
