Brachiopods are animals that live inside two shells (or valves) that show bilateral symmetry from side to side (i.e., if viewed from above or below). The top and bottom shells are not the same shape. To see this, look at the Side view in Figure 7.9: the valve on the left is the top and the valve on the right is the bottom.

Both bryozoans and echinoids lived throughout the fossil record and thus are not good index fossils. In contrast, rugosa and brachiopods are both more limited in their age range.

Countless billions accumulated on the ocean floor in over 30,000 forms. The dominance of Paleozoic articulate brachiopods in once-muddy environments may be explained by an array of mechanisms and structures that reject nonfood particles, in some cases without interruption of feeding: (1) behavioral flexibility of the lophophore and its individual filaments; (2) persistent, variable-speed rejection currents on the mantle, which …Brachiopods can perhaps be best described as a type of shellfish quite unlike other types of shellfish.
