Teleochilus balcombensis is an extinct species of sea snail, a marine gastropod mollusc in the family Raphitomidae.[1] Fossils of the species date to the middle Miocene, and have been found in strata of the Port Phillip Basin of Victoria, Australia.
Description
[edit | edit source]
In the original description, Powell described the species as follows:
Shell of moderate size, slender, subcylindrical, but with the spire-whorls noticeably convex. Aperture about half height of shell. Post-nuclear sculpture of 8-9 flat-topped, moderately strong cords, with inter-spaces averaging half their width. Two to four cords on the median area of the body-whorl are bifurcated by a linear groove. There are 26 primary cords on the body-whorl. Shoulder sulcus distinct, situated below the first subsutural cord. Axial sculpture of weak, wide-spaced folds on first 2-3 whorls.[2]
The holotype of the species measures 18 mm (0.71 in) in height and 6 mm (0.24 in) in diameter.[2]
Taxonomy
[edit | edit source]The species was first described by A.W.B. Powell in 1944.[2] The holotype was collected from Fossil Beach of Balcombe Bay, Mornington, Victoria at an unknown date prior to 1944, and is held by the Auckland War Memorial Museum.[3][4]
Distribution
[edit | edit source]This extinct marine species dates to the middle Miocene (Balcombian), and occurs in the strata of the Port Phillip Basin of Victoria, Australia, including the Gellibrand Formation.[3][5]
