Rhynchonelliform brachiopod Triassic-Recent

This Recent brachiopod lives in Australian and Antartic waters at a depth of between 12 and 600 m. It measures approximately 3 cm from the pedicle opening to the anterior edge. Using its stout pedicle it attaches to hard substrates. The pedicle acts as a stalk and raises the brachiopod from the attachment surface. The lophophore is supported by a distinctive calcareous loop attached to the hinge area of the dorsal valve. This structure is only rarely preserved in fossil brachiopods.
