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

Etymology
editThe genus name Tubospirina combines the Latin word tubus, meaning "tube" and the genus name Spirina.[2]
Description
editThe 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.[2]
