Orders


Traditionally, the Myodocopa and Podocopa have been classified as subclasses within the class Ostracoda, although there is some question about how closely related the two groups actually are. The Myodocopa are defined by possession of a poorly-calcified carapace, and 8-9 articles in the exopod of the second antenna. (Kornicker, 1993). The ventral margin of the carapace is not concave, and the valves do not overlap to a great extent (Horne, 2002).

Although the carapace of myodocopans is poorly-calcified, some fossils are known for the group. (In contrast, thousands of fossil species are named for the Podocopa). Of particular interest are those fossils for which the internal body parts (and not just the carapace) are preserved. This provides a lot more information about the likely relatives to the fossil taxa, including relatives still alive today. Two recent fossils of much interest have been found from Silurian deposits (dated at 425 million years ago). These fossils have well preserved internal body parts (Siveter et al 2003, Siveter et al 2007).

Scientific classification or biological classification is a method by which biologists group and categorize species of organisms. Scientific classification also can be called scientific taxonomy, but should be distinguished from folk taxonomy, which lacks scientific basis.

Georg Ossian Sars (April 20 1837 - April 9 1927) was a Norwegian marine biologist.

Like his father, Michael, Georg Sars was a marine taxonomist, and is credited with the discovery of a number of new species, particularly mysids and ostracods.

order (Latin: ordo, plural ordines) is a rank between class and family (termed a taxon at that rank). The superorder is a rank between class and order. Exact details of formal nomenclature depend on the Nomenclature Code which applies.

The Podocopa are a subclass of ostracods. This subclass can be differentiated from the other subclass (Myodocopa) by the morphology of the second antenna: the Podocopa have a relatively long endopod,

A carapace is a dorsal section of an exoskeleton or shell in a number of animal groups.

Crustaceans

In crustaceans, the carapace is a part of the exoskeleton that covers the cephalothorax. It is particularly well developed in lobsters and crabs.

Antennae (singular antenna) are paired appendages connected to the front-most segments of arthropods. In crustaceans, they are biramous and present on the first two segments of the head, with the smaller pair known as antennules.
