Scrinium duplicatum is an extinct species of sea snail, a marine gastropod mollusc in the family Mitromorphidae.[1] Fossils of the species date to the early Miocene, and occur in the strata of the Port Phillip Basin of Victoria, Australia.
Description
In the original description, Powell described the species as follows:
Resembles [Scrinium haroldi], but slightly larger, more robust, with a depressed. dome-shaped protoconch, medially angulate whorls, and a moderately strong subsutural fold bearing two linear-spaced spiral cords. Whorls 6, including protoconch. Axials heavy, broadly rounded, not extended over base, 8-10 per whorl (8 on penultimate, in holotype). Spiral sculpture of regular linear-spaced cords, 14 on the penultimate (including two on subsutural fold), and about 38 on body-whorl and base.[2]
The holotype of the species measures 10 mm (0.39 in) in height and 4.5 mm (0.18 in) in diameter.[2]
Taxonomy
The species was first described by A.W.B. Powell in 1944.[2] The holotype was collected from Torquay, Victoria, at an unknown date prior to 1944, and is held by the Auckland War Memorial Museum.[3][4]
Distribution
This extinct marine species dates to the early Miocene, and occurs in the strata of the Port Phillip Basin of Victoria, Australia, known from the Puebla Formation.[3][5]
