The earliest ostracods: the geological evidence SpringerLink
WebOstracods are by far the most complex organisms studied within the field of micropalaeontology. They are Metazoa and belong to the Phylum Arthropoda (as trilobites), Class Crustacea (as lobsters and crabs). An important distinguishing feature Ostracods share with other arthropods is the bilateral symmetry of their body form. WebPhosphatocopida Müller, 1964, is a group of small crusta-ceans having a secondarily phosphatized bivalved dorsal shield, which covered the entire body but was attached only to the head and the anterior two or three trunk segments.
