Micropilina

Micropilina is a genus of monoplacophoran mollusks. They are very small, mostly deepwater animals which have a superficially limpet-like shell.
In addition to a number of living, deep-sea species, this genus also includes a shallow water fossil from the middle Pleistocene of Italy - and this is the only fossil representative of this lineage subsequent to the Devonian period.
All currently known "Micropilina" species are less than 1.5 mm in length. Except for "Micropilina minuta", they are all found in the Southern Hemisphere.
