== Morphology ==
Limpet-like ''Marocella '' is a low conical shell with concentric ridges that grew to a couple of centimetres in length.<ref name="ReferenceA">{{Cite journal | last1 = Skovsted | first1 = C.

== Affinity ==
''Marocella'' is thought to be a mollusc, although its position within this [phylum](/source/phylum) is undetermined.<ref name="ReferenceA"/>  Relationship to the [halkieriids](/source/Halkieria) has also been considered.<ref name="ReferenceB"/>

== Ecology ==
Some specimens show evidence of repairing damage caused by predators.<ref name="ReferenceA"/>  It probably moved around on the sea floor.<ref name="ReferenceA"/> It was geographically widespread.<ref name="ReferenceA"/>
