While searching the vast “behind the scenes” fossil collections of the Paleontological Research Institution, museum staff discovered a most unusual brachiopod specimen at the back of a drawer that had …Brachiopods are marine animals that, upon first glance, look like clams. They are actually quite different from clams in their anatomy, and they are not closely related to the molluscs. They are lophophorates, and so are related to the Bryozoa and Phoronida. Although they seem rare in today's seas, they are actually fairly common.Strophomenoid brachiopods. These brachiopods can become rather large, some having shells of 75 mm (3 inches) in diameter. Their pedicle opinings are usually filled with small calcite plates.

Brachiopods have one of the longest histories and best fossil records of all invertebrates. Here they lived in the mud or were attached to the sea floor, filter-feeding on organic particles carried by ocean currents. Most were attached to a surface by a fleshy stalk that protruded through a hole at the shells’ hinge.Brachiopods are extremely common fossils throughout the Palaeozoic. During the Ordovician and Silurian periods, brachiopods became adapted to life in most marine environments and became particularly numerous in shallow water habitats, in some cases forming whole banks in much the same way as bivalves (such as mussels ) do today.In older classification schemes, phylum Brachiopoda was divided into two classes: Articulata and Inarticulata. Since most orders of brachiopods have been extinct since the end of the Paleozoic era 251 million years ago, classifications have always relied extensively on the morphology (that is, the shape) of fossils.In the last 40 years further analysis of …Fossil Info.

The calyx and the holdfast are only occasionally preserved as fossils. Crinoids are still around today; those in shallow water are mostly stalkless, while those with stalks are restricted to deep water. Fossils are often said to take a million years to form. However, as of 2014 it has been proven that a fossil can take a shorter period of time to form. This period can be a thousand years or less.Two more brachiopod genera are shown in this figure, Juresania the top two and Meekella the bottom three (photograph slightle enlarged).

Ordovician. In the Ordovician Period, Britain lay south of the equator and had a cool climate. Seas covered Britain and there was dramatic volcanic activity as the ocean separating England and Wales from Scotland started to close.A relatively common Cambrian fossil is the brachiopod.
