Megasurcula tremperiana is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies.[1]

Taxonomy

[edit]

There is some confusion about the accepted name for this species. The website Gastropods.com considers this species a synonym of Mangelia carpenteri (Folin, L. de, 1867) It was also considered a synonym of Bathytoma tremperiana (Dall, 1911),[2] itself considered by W.H. Dall a synonym of Cryptoconus tremperianus Dall, 1911.[3] But then WoRMS considers this last name a synonym of Megasurcula carpenteriana (Gabb, 1865)[4]

Description

[edit]

The sea snail Megasurcula tremperiana has a shell that, in the adult stage, typically reaches a length of around 60 mm (2.4 inches). It is known for being a relatively large and ponderous species within the genus Megasurcula. While M. carpenteriana is also large, M. tremperiana is slightly smaller in size, with a shell length averaging about 62 mm.

Distribution

[edit]

Megasurcula tremperiana is a marine snail species found off the coast of California, USA. Fossils of this species have also been found in Miocene strata in Venezuela. The snail is part of the Pseudomelatomidae family and the genus Megasurcula. It is known from both living specimens found in the coastal waters of California and as fossils in Miocene sediments.
