Marocella is a conical shelly fossil of uncertain affinity (probably a mollusc) known from Cambrian strata of Europe, Morocco, Australia and Antarctica.[2]
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]
Distribution
Fossils of Marocella have been found in:[4]
- Shackleton Limestone, Antarctica
- Mernmerna Formation and Parara Limestone, Australia
- Jbel Wawrmast Formation, Morocco
- Sparagmite Formation, Norway
- Láncara Formation, Spain
