They are often known as “lamp shells”, since the curved shells of the class Terebratulida look rather like pottery oil-lamps.Cross sectional views through the valves of shelled animals such as brachiopods and bivalves are most common. If two valves are preserved, and the valves are the same (mirror images) the fossil may be a bivalve (clam). If two valves are preserved, and the valves are slightly different in shape, the fossil is probably a brachiopod.Brachiopods (Figure 7.9) range from the Lower Cambrian to the present. They were at peak diversity in the Devonian, but most went extinct at the end of the Permian. Brachiopod fossils are often well-preserved, as well as being abundant and exhibiting diverse shell morphology (i.e., a variety of shell shapes) over time.The geographic population patterns of Lingula anatina across the Indo-West Pacific region are analyzed based on mitochondrial COI and nuclear EF-1α gene sequences.

Brachiopod fossils have shells that look like wings. They help you to release old ideas that are bogging you down, and to thus inwardly “fly.” In China, this type of brachiopod is know as a Stone Swallow; in the European alps they are called Little Doves and in Delabole, Cornwall, England they are called “Delabole Butterflies.”Fossils from this phylum of “moss animals”—the translation of bryozoan from Greek—have been found as far back as the Early Ordovician (~480 million years ago). ... which is used in this chapter to refer exclusively to the Ectoprocta—were subsequently grouped with the Phoronida and Brachiopoda, in 1891, on the basis of their similar ...Brachiopod fossils have shells that look like wings.

Brachiopods are marine, shelled organisms that lived in both shallow and deep water environments. Brachiopod shells superficially resemble clam shells. However, there is a trick to differentiating between the two. There are about 100 to 350 species living; the fossil species number 12,000. Lingula, one of the oldest genera of brachiopods, has survived from the earliest Ordovician to the present day. The various species look very similar, and the genus is a good example of a living fossil. Brachiopod classification is being debated by invertebrate ...

A Modern Day Brachiopod. Brachiopods are an ancient group of organisms, at least 600 million years old. They might just look like clams, but they are not even closely related. Instead of being horizontally symmetrical along their hinge, like clams and other bivalves, they are vertically symmetrical, cut down the middle of their shell.
