Morphology

edit

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

Affinity

edit

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

edit

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]

Distribution
