Marrellomorpha: Art, Taxonomy & Description and ecology

Marrellomorpha are an extinct group of arthropods known from the Cambrian to the Early Devonian. It is divided into two major groups, Marrellida and Acercostraca. They lacked mineralised hard parts, so are only known from areas of exceptional preservation, limiting their fossil distribution. The best known member is Marrella, with thousands of specimens…
