This invertebrate shelled animal that is exclusively marine, is made up of two separate shells or valves. These valves are unlike and unequal in size.
The various types of fossil brachiopods are found in different rock formations.
Brachiopods became prominent in the oceans during the Paleozoic period.
The living brachiopod has an “arm” (brachio) which attaches the shelled animal to the sea floor or other sea objects. There are fewer of these specimens alive today.
