Uberella marwicki

Uberella marwicki is an extinct species of sea snail, a marine gastropod mollusc, in the family Naticidae. Fossils of the species date to early Miocene strata of the west coast of the Auckland Region, New Zealand.

Description

In the original description, Powell described the species as follows:
The holotype of the species measures in length and has a diameter of. The species can be differentiated from other members of Uberella due to having a very large lower columella and basal lip, and due to the semi-circular gap in the species' callus above its small umbilicus.

Taxonomy

The species was first described by A. W. B. Powell in 1935, who named the species after New Zealand palaeontologist John Marwick. The holotype was collected at an unknown date prior to 1935 from fallen rocks at the southern end of Maukatia Bay, south of Muriwai, Auckland Region, and is held in the collections of Auckland War Memorial Museum.

Distribution

This extinct marine species occurs in early Miocene strata of the Nihotupu Formation of New Zealand, on the west coast of the Waitākere Ranges of the Auckland Region, New Zealand.
