Gastrocopta sp. from the Viernheim borehole is an undescribed species of a very small fossil land snail, a terrestrial pulmonate gastropod mollusc in the family Gastrocoptidae.
Distribution
[edit]There is only one record of this species from 2008 from the Viernheim research borehole, Germany from the Lower Pleistocene (Lower Biharium).[1]
Description
[edit]The small conical shell is 1.9 mm high and 1.0 mm wide.[1] The five arched whorls increase uniformly in size up to the penultimate whorl – the last whorl becomes smaller towards the aperture.[1] The apertural border with the lip is well formed and slightly folded over towards the spindle.[1] The shell is shiny, slightly stripy and has a weakly developed palatine torus.[1] It has three strong teeth, one columellar, one palatal and one parietal, although the adjacent palatine wall of the specimen is damaged and partially missing.[1] The teeth are almost the same distance apart and their tips almost point towards one another.[1] A characteristic feature is the complete absence of a basal tooth.[1]
