Leptanena depressa (J Sowerby, 1824). BGS © UKRI.In Michigan, brachiopods can be found in rocks ranging from the Ordovician to Mississippian (485 – 323 million years ago). Brachiopod fossils are commonly found in Paleozoic rocks, as they were especially abundant then, but brachiopods can sometimes be found in today’s oceans from tropical waters to the freezing Arctic and Antarctic waters.Cross sectional views through the valves of shelled animals such as brachiopods and bivalves are most common. If two valves are preserved, and the valves are the same (mirror images) the fossil may be a bivalve (clam). If two valves are preserved, and the valves are slightly different in shape, the fossil is probably a brachiopod.

In fact, brachiopods are more closely related to another group of animals with lophophores that are also common in Cincinnatian rocks, the Phylum Bryozoa. The easiest way to distinguish a fossil brachiopod from a fossil clam (which also occur in Cincinnatian rocks) is to determine where the line of symmetry falls between the two valves. Scientists have divided the invertebrates into 33 phyla of which 25 have a fossil record, and of these 25 phyla 15 are represented in the Field Museum’s collections (see fossil photo gallery ). Approximate representation by major groups in the collection is: Porifera 5%. Cnidaria 11%. Bryozoa 5%. Brachiopoda 17%.Quartzites, slates, shales, limestones and dolomites have produced identifiable fossils. The quartzites are the least productive.

Crinoid fossils are most commonly found as "columnals," pieces of the stalk that hold the head (calyx) above the surface. The calyx and the holdfast are only occasionally preserved as fossils.
