Instead, …Present-day types of bryozoan involvement in coral reefs go back to at least mid-Cenozoic time (approximately 30 ma). Miocene, Pliocene, and Pleistocene fossil reefs often exhibit bryozoan crusts among the corals in the same manner seen on living reefs, as figured in the Late Pleistocene (125 ka) reefs in the Florida Keys (Cuffey, 1977, p. 187–188) and noted in the Early Miocene uplifted ...Ohio is a great state for viewing and collecting fossils. All of the state's bedrock (consolidated rock underlying soil and till) exposed at the Earth's surface is sedimentary rock, and most of it contains fossils. Some rocks, such as many Ordovician-age limestones of southwest Ohio, are primarily composed of fossils.Bryozoans are very small, colonial animals. In mass, they combine to form mats, mounds, branches, fans, or lacy fronds. Tentacles surrounding their mouths grabbed microscopic organisms floating in the water. These animals differ from coral in that they lived in pits on the surface of the structure and not in radiating partitioned cups.Anatomy Shell structure and function An articulate brachiopod: Pedicle (ventral) valve Brachial (dorsal) valve Pedicle Surface Modern brachiopods range from 1 to 100 millimetres (0.039 to 3.937 in) long, and most species are about 10 to 30 millimetres (0.39 to 1.18 in). Magellania venosa is the largest extant species. The largest brachiopods …Fossils are the evidence in rock of the presence of a plant or an animal from an earlier geological period. Fossils are formed when minerals in groundwater replace materials in bones and tissue, creating a replica in stone of the original organism or of their tracks.

Fossils are the traces or remains of organisms buried and preserved in sediments. They consist not only of hard body parts, such as bone and shell, but also may be impressions of plants, or tracks, trails, and burrows. Fossils can tell us what life was like on Earth in ancient geologic time, helping geologists describe ancient depositional environments and understand past climates. Fossils ...Ancient Coral. Petosky stone is a fossil rock formed from the remains of the rugose coral Hexagonaria percarinata. These corals are believed to have existed before the dinosaurs and thrived during a time when a warm, shallow sea covered a large part of the Great Lakes region. At that time a large reef supported an abundant variety of sea life ...Phylum Bryozoa – Bryozoa are tiny filter-feeding colonial organisms which build a calcium carbonate structure which have varied appearances (lacy fans, corkscrews, and twig-like shapes are common).
