Braciopods

Brachiopods alive today live in cold, marine environments like polar seas and the continental shelf and continental slope. The diversity of fossil species suggests that Devonian Brachiopods occupied most of the marine environments that existed at the time. It is likely that they lived in cold polar waters and warm seas, from the deep ocean to ....

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.Braciopods. Share. Did you know?

The most common fossils found in Pennsylvania are of the phylum Brachiopoda, coming from the Greek "brachion" meaning 'arm' and "podus" meaning 'foot', and better known as brachiopods (BRAK-ee-oh-pods).

Brachiopods are abundant and tend to be more numerous in the lowermost part (5-8 m) of the Member.This is a distinctive character difference between brachiopods and bivalves. The plane of symmetry in bivalves is between the valves, making them mirror images. This plane would be equivalent to the commissural plane in brachiopods.

Mucrospirifer, genus of extinct brachiopods (lamp shells) found as fossils in Middle and Upper Devonian marine rocks (the Devonian Period began 416 million years ago and lasted about 57 million years). Mucrospirifer forms are characterized by an extended hinge line of the two valves, or shells, of the brachiopod and a prominent fold and sulcus—a bow … ….

Evolution of brachiopods. The Devonian brachiopod Tylothyris from the Milwaukee Formation, Milwaukee County, Wisconsin.
