Species belonging to the genus lived from the Middle Ordovician ( Sandbian) through to the Late Triassic ( Carnian) with a global distribution. They were stationary epifaunal suspension feeders. [1]The most obvious aspect of a Brachiopod is its shell. This shell is a hard, solid object that often remains intact long after the animal is dead. This is why we have such a good fossil record of the Brachiopoda. The shell is composed of about 50% calcium carbonate or phosphate, which the animal extracts from the sea water.
