Fenestrodaphne

Fenestrodaphne is a genus of minute gastropod molluscs belonging to the superfamily Conoidea, currently unassigned to a family. The genus is a monotypic fossil taxon, currently known to only have one member, Fenestrodaphne pulchra. It is known to occur in the middle Miocene in fossil beds of South Australia.

Description

In the original description, Powell described the genus and species as below:
The holotype measured in height, with a diameter of.

Taxonomy

Both the genus and species were first described by A. W. B. Powell in 1944 in the same paper, noting the species' similarity to Asperdaphne. The holotype of the species is held by the Auckland War Memorial Museum. Alan Beu in 2011 also noted the species' similarity to Asperdaphne tasmanica, suggesting that both species may be in the genus Taranis. While part of the superfamily Conoidea, the genus was excluded from the family Turridae by Yu I Kantor et al. in 2024.

Distribution

The species is known to have lived in the Middle Miocene, and has been found in the lower Dry Creek Sands, Metropolitan Abattoirs Bore of the St Vincent Basin, in Adelaide, South Australia, at a depth of between.
