Some Silurian brachiopods lacked a stalk, had a flattened shell form (figure 3b), and rested freely on the seafloor. At least 43 species of brachiopods represent the most diverse group of dwellers in the Silurian reefs of Wisconsin. The ten species shown above can be found in the Silurian reef diorama. The oldest brachiopods can be found in rocks of early Cambrian age (about million years old). They are still alive today. Can I find them in Oklahoma? Brachiopods can be found in Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Cretaceous rocks. They are particularly common in Ordovician-Carboniferous rocks.

About this book Late Hirnantian and early Rhuddanian shelly faunas dominated by brachiopods are well developed in the clastic facies succeeding the cool and deep-water, very-low-diversity Hirnantia fauna in Zhejiang and Jiangxi provinces, south-east China; elsewhere in the world, during this interval, brachiopod assemblages are generally rare.

The brachiopod Stegerhynchus Foerste, occurs in Silurian strata in Canada, the U.S.A., the U.S.S.R., Gotland, and the United Kingdom. Review of the literature shows that Rhynchonella whitii praecursor Hall, is the true type species of Stegerhynchus.

Brachiopod Diversity Patterns. Brachiopods have one of the longest fossil records of any multicellular animal. Brachiopods have been the most abundant bottom-dwelling creatures for three out of five global mass extinction events, all of which occurred during the Paleozoic era.   SUPERFAMILY- Triplesiacea. Its impunctate,generally biconvex brachiopods having flate deltidium. Middle Ordovician through Silurian. SUPERFAMILY- Syntrophiacia. Generally smooth shells having strongly developed pedical plica and brachial sulcus. Middle Cambrian into lower Devonian. SUPERFAMILY- Plectambonitacea.
