Syntomodrillia ludbrookae is an extinct species of sea snail, a marine gastropod mollusc in the family Drilliidae.[1] Fossils of the species date to the middle Miocene, and have been found in the strata of the St Vincent Basin of South Australia.
Description
[edit]
In the original description, Powell described the species as follows:
Whorls very lightly convex, peripheral angle scarcely apparent, defined only by a slight thickening of the axials at about the middle. Axials narrow-crested, oblique, flexuous over body-whorl, fading out on middle of base, 15-16 per whorl. Anterior end with 5 distinct spiral threads.[2]
The holotype of the species measures 7 mm (0.28 in) in height and 2.7 mm (0.11 in) in diameter.[2] It has a similar appearance to Tylotiella falcicosta found in KwaZulu-Natal, South Africa, but has a slightly more narrow shell.[3]
Taxonomy
[edit]The species was first described by A.W.B. Powell in 1944.[2] The holotype was collected from the Metropolitan Abattoirs Bore in Adelaide, Australia, at a depth of 122–152 m (400–499 ft) in 1919 by Walter Howchin and Joseph Verco, and is held by the Auckland War Memorial Museum.[4][5]
Distribution
[edit]This extinct marine species dates to the middle Miocene, and occurs in the strata of the St Vincent Basin of South Australia, found in the Dry Creek Sands.[4][6]
