Brachiopods fossils
Brachiopods are extremely common fossils throughout the Palaeozoic. During the Ordovician and Silurian periods, brachiopods became adapted to life in most marine environments and became particularly numerous in shallow water habitats, in some cases forming whole banks in much the same way as bivalves (such as mussels ) do today.
