Paleozoic

The history of brachiopods probably starts in Lower Cambrian.The oldest fossils go back to this time. Kutorgina and Acrothele belong to the Cambrian genera. From then on and until the Permian, the brachiopods do not cease diversifying. However, it is in the Lower Devonian that they know their greatest evolutionary diversity, the number of species becomes considerable then.

Permian

Peniculauris bassi
(Mc Kee)
Arizona / USA

The mass extinction at the end of the Permian had a great influence on the brachiopods. Nearly 83% of the marine species disappeared. Several groups of brachiopods were among the victims. (Buffetaut, E., 1992).
