Spiriferid brachiopod.
Dec 1, 1990 · Based on fluid mechanical considerations, a mode of life for the spiriferid Austrospirifer variabilis Glenister is presented. This palaeoecological model suggest that, in an environment where the water currents were at least of the order of 0.5 m/s. the spiriferid, anchored to the substrate by its pedicle, flew in the water in much the same way as a kite flies in air.

Spiriferid are brachiopods filtering feeders that fed on organic particles washed around by the ocean currents. The valves (each shell side) has pronounced folds and sulcus (furrow, fissures). They lived in mud by anchoring to the sea floor with a fleshy stalk called a pedicle that protruded from the shell’s hinge.

Spiriferida is an order of extinct articulate brachiopod fossils which are known for their long hinge-line, which is often the widest part of the shell. In some genera (e.g. Mucrospirifer) it is greatly elongated, giving them a wing-like appearance. They often have a deep fold down the center of the shell.

The easiest differences to identify are in the shells of clams and Brachiopods. Mollusk shells are divided into left and right while Brachiopod shells are divided top (dorsal) and bottom (ventral). The shells of mollusks are usually equal on the right and left.
