No records of brachiopods are known from the Precambrian. ... They first appear in the Cambrian and many disappear in mass extinction of Permian. Although some survive; even to the present, never ...Brachiopods first appeared over 500 million years ago, and some types (such as Lingula, which lives in a burrow) have changed very little over this period of time. However, brachiopods are quite rare today. In Britain they are only found in a few Scottish sea-lochs. On the right, shells of recent brachiopods, including the genus Lingula.Modern brachiopods have very little living tissue and thick shells, and this was almost certainly true in extinct species as well. They have therefore been considered to not be worthwhile prey, given the small reward. However, recent observations on modern brachiopod populations reveal they may not be completely safe from predation. Brachiopod Fossils.

They were at peak diversity in the Devonian, but most went extinct at the end of the Permian. Brachiopod fossils are often well-preserved, as well as being abundant and exhibiting diverse shell morphology (i.e., a variety of shell shapes) over time. When did bivalves take brachiopods? Before the worst mass extinction of life in Earth’s history — 252 million years ago — ocean life was diverse and clam-like organisms called brachiopods dominated. After the calamity, when little else existed, a different kind of clam-like organism, called a bivalve, took over.Fossils of many types of water-dwelling animals from the Devonian period are found in deposits in the U.S. state of Michigan. Among the more commonly occurring specimens are bryozoans, corals, crinoids, and brachiopods. Also found, but not so commonly, are armored fish called placoderms, snails, sharks, stromatolites, trilobites and blastoids .
