      Abstract. Brachiopods of the order Orthida from the Lower and Middle Devonian of northeastern Russia: Skenidium diversus Baranov (family Skenidiidae); Datnia gen. nov., with the type species D. asiatica sp. nov.

Brachiopods differ in many ways from bryozoans (in both soft and hard-part morphology), and are thus considered by most workers as a separate but closely related phylum. However, one of the most distinguishing features of brachiopods is the presence of a pedicle, a fleshy stalk-like structure that aids the animal in burrowing and maintaining.

Abstract. Traditionally, Brachiopoda (sensu lato) is regarded as a distinct phylum of lophophorate animals and is divided into two major taxa, Class Inarticulata (or Ecardines) and Class Articulata (or Testicardines).Both taxa are polythetic, but their diagnoses are based mainly on two features: the presence or absence of the articulation of the valves, and an open or blind digestive by:

Order Orthida (Cambrian-Permian) The orthid brachiopods were the first important articulate group to diversify, and appeared during the Early Cambrian period, and became very diverse during the Ordovician.

They are typically strophic having a straight hinge line), and well developed interareas. Brachiopods of the order Orthida in Czechoslovakia (in english) Artikelnummer: P Edition: Rozpravy ÚÚG No. 44, Prag Havlíček V. () The author is continuing his study of Bohemian and Moravian Paleozoic brachiopods.

Orthida is an extinct order of brachiopods which appeared during the Early Cambrian period and became very diverse by the Ordovician, living in shallow-shelf seas. Orthids are the oldest member of the subphylum Rhynchonelliformea, and is the order from which all other brachiopods of this group stem.

Physically they are usually strophic, with well-developed interareas. They also commonly have Clade: Lophophorata. Books; Order items by.

The order Orthida contains the oldest members of the Rhynchonelliformea and is the stem group for all other brachiopods in this subphylum. The content above is only an excerpt.

You may already have access to this content. The Orthida, are an assemblage of extinct Paleozoic stocks that include the oldest known rhynchonellate brachiopods. They were especially prolific during the Cambrian and Ordovician and became so diversified as to anticipate many of the morphological characteristics of other rhynchonellates.

Brachiopods are virtually defenceless and their shell, enclosing the animal's organs, is their only protection. Most are permanently attached by a fleshy stalk (the pedicle) to a hard, sea-floor surface, such as a rock outcrop, boulder or some other shell, and are incapable of actively pursuing food.

Brachiopods have metanephridia, used by many phyla to excrete ammonia and other dissolved wastes. However, brachiopods have no sign of the podocytes, which perform the first phase of excretion in this process, and brachiopod metanephridia appear to be used only to emit sperm and : Lophophorata.

Brachiopod morphology and terminology; Brachiopods versus bivalves Brachiopods superficially resemble clams but are not closely related to our modern sea shells. Clams, or bivalves, belong to the Class Bivalvia in the Phylum Mollusca, while brachiopods belong to their own phylum, Brachiopoda.

() The author is continuing his study of Bohemian and Moravian Paleozoic brachiopods. Primary consideration is given to taxa of the suborder Orthidina, which is richly represented in the Bohemian and Moravian Paleozoic.

Order Orthida (Cambrian to Permian) Orthids were some of the earliest rhynchonelliform brachiopods to diversify. Distinguishing characteristics include a strophic hinge line and shell that is typically ornamented with strong ribbing.

The brachiopods have for a long time been traditionally divided into two classes, the Inarticulata and the Articulata.
