Along with …The origin of the brachiopods is uncertain; they either arose from reduction of a multi-plated tubular organism, or from the folding of a slug-like organism with a protective shell on either end.

[2] The renaming of phyla such as Firmicutes in 2021 remains controversial among microbiologists, many of whom continue to use the earlier names of long standing in the literature. [3]The brachiopod shell is a multilayered complex of both organic and inorganic material that has proven to be of fundamental importance in the classification of the phylum. The shells of most rhynchonelliformean brachiopods consist of three layers (Figure 4). The outer layer (periostracum) is organic, whereas underneath are the mineralized ...Only about 300 to 500 species of brachiopods exist today, a small fraction of the perhaps 15,000 species (living and extinct) that make up the phylum Brachiopoda. Brachiopod shells come in a variety of shapes and sizes. Sometimes the bottom valve is convex like the top valve, but in many species the bottom valve is concave or occasionally conical.

Brachiopods, or lampshells, are a phylum of small marine animals with a two-valved shell that, at first glance, resemble bivalved mollusks such as clams. The resemblance, however, is quite superficial. ThePhylum Brachiopoda (Cambrian to Recent) Brachiopoda is a phylum of marine animals whose soft bodies are enclosed by a shell consisting of two halves (valves). In this way they resemble clams, but their soft-part anatomy differs considerably from that of clams. Furthermore, the nature of the valves is quite different from that of clams.…
