It diversified significantly after the end-Permian extinction and became one of the four major clades of Triassic brachiopods.Fossil spiriferids first appear in the Ordovician period, as illustrated in the fossil range chart for brachiopods. They were extremely diverse during the Devonian period and later went extinct during the Jurassic period. Some fossil brachiopods make spectacular finds, like this one preserved as pyrite (fools gold).

Members of this group can have punctate or impunctate shell microstructure, strophic or astrophic hinge line, and of any of a number of gross shell morphology.
