Paraguraleus incisus

Paraguraleus incisus is an extinct species of sea snail, a marine gastropod mollusc in the family Mangeliidae. Fossils of the species date to the middle Miocene, and have been found in strata of the St Vincent Basin of South Australia, Australia.

Description

In the original description, Powell described the species as follows:
The species has an axial sculpture of sinuous costae. The holotype of the species measures in height and in diameter, while another specimen seen by Powell measured by.

Taxonomy

The species was first described by A.W.B. Powell in 1944, as Guraleus incisus. The species was moved to the genus Antiguraleus in 1970 by Thomas A. Darragh due to its distinctive curved costae and outer lip supported by a thick external varix, This recombination is not supported by the World Register of Marine Species, which gives the accepted name of the species as Paraguraleus incisus. The holotype was collected in 1919 by Walter Howchin and Joseph Verco from the Metropolitan Abattoirs Bore in Adelaide at a depth of between, and is held by the Auckland War Memorial Museum.

Distribution

This extinct marine species occurs in middle Miocene strata of the St Vincent Basin of South Australia, including the lower Dry Creek Sands Formation.
