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

Affinity
Marocella is thought to be a mollusc, although its position within this phylum is undetermined. Relationship to the halkieriids has also been considered.

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

Distribution
Fossils of Marocella have been found in:
 * Shackleton Limestone, Antarctica
 * Mernmerna Formation and Parara Limestone, Australia
 * Jbel Wawrmast Formation, Morocco
 * Sparagmite Formation, Norway
 * Láncara Formation, Spain
