以腕足动物为主的古生代海床被一系列生物的迁移和恢复所改变。寒武纪和古生代演化动物群的生态学和分类学动力学在寒武纪晚期、奥陶纪末、泥盆纪晚期和二叠纪末被多个系列的灭绝所打断。虽然在古生代期间，三角齿类和喙突齿类之间的平衡得以维持，但在早古生代至中古生代期间，orthides和strophomenides的主导作用被晚古生代期间的产物所取代。三角齿类的形态在二叠纪末的灭绝中没有幸存下来;现代有关节的腕足动物群主要是带有脚和环的无关节齿类。然而，一个反复出现的趋势是广泛分布的腕足动物分类群的长期成功，以及在灭绝阶段之间的间期进化的更专业和高度适应的变体的消亡，这些变体具有更有限的分布。版权所有© 2001约翰威利父子有限公司。
The brachiopod‐dominated seabeds of the Palaeozoic were modified by a series of biotic extinctions and recoveries. The ecologic and taxonomic dynamics of the Cambrian and Paleozoic Evolutionary Faunas were interrupted during the late Cambrian, end‐Ordovician, late Devonian and end‐Permian by a multiple series of extinctions. While the balance between the deltidiodont and cyrtomatodont rhynchonelliformeans was maintained during the Palaeozoic, the dominant role of the orthides and strophomenides during the early to mid‐Palaeozoic was usurped by the productides during the late Palaeozoic. The deltidiodont morphology did not survive the end‐Permian extinctions; the modern articulated brachiopod fauna is dominated by cyrtomatodonts with crurae and loops. Nevertheless, a recurring trend is the long‐term success of brachiopod taxa with widespread distributions and the demise of the more specialized and highly adapted morphs having more restricted distributions commonly evolved during interregna between phases of extinction.
