Morphology

Limpet-like Marocella is a low conical shell with concentric ridges that grew to a couple of centimetres in length.^[3]

Affinity

Marocella is thought to be a mollusc, although its position within this phylum is undetermined.^[3] Relationship to the halkieriids has also been considered.^[2]

Ecology

Some specimens show evidence of repairing damage caused by predators.^[3] It probably moved around on the sea floor.^[3] It was geographically widespread.^[3]
