Austrotoma deducta is an extinct species of sea snail, a marine gastropod mollusk in the family Pseudotomidae.[1]
Description
The subsutural fold is weak to moderately developed, while the spiral sculpture remains the dominant feature across the entire shell. Axial elements are absent on the body whorl, with approximately 16 present on each preceding whorl. The spire is relatively low, measuring less in height than the aperture.[2]
Distribution
Fossils have been found in Upper Miocene strata at Gisborne, New Zealand.[2]
