Provanna

Provanna is a genus of sea snails, marine gastropod mollusks in the family Provannidae.[1]

The species was named after Dall's first wife.

This is a very old genus with species already existing in Cretaceous seep deposits off Japan (93 - 100 million years ago). The Caribbean and the Pacific fauna were isolated about 3 million years ago by the closure of the Central American Isthmus.

Description[edit]

The apical whorls of the protoconch are lacking through decollation. The opening is then sealed with a calcareous plug. The sculpture of the ovate fusiform shell shows scattered sigmoidal axial ribs that are crossed by spiral cords. The whorls are broad.

Habitat[edit]

They are common in hydrothermal vents, hydrocarbon cold seeps and (more rarely) on deep-water food-falls, depending on the species. Most species feed on filamentous bacteria, while others feed on detritus.

Species[edit]

Species within the genus Provanna include:

Several fossil species also have been described, predominantly identified from hydrocarbon seep deposits (Saether et al., 2010), including:

There also are several fossil species known, but not formally described and named, from central America, Japan, and possibly the Philippines (see Saether et al., 2010).
