No. Genus: Juresania Extinct brachiopod with a highly convex (curves outward) pedicle valve. Juresania lived on the seafloor, propped up out of the mud by long spines. Fossil valves are covered with the broken spine bases. Abundant Mississippian - Permian Fossils can be found in Texas Pennsylvanian rocks. 1) What valve does picture A represent? pedicle or brachial valve 2) Was this a benthic epifaunal or infaunal brachiopod? 3) What feeding habit best describes Juresania? (suspension-feeder or sediment-feeder) 4) Do you find evidence of broken spines on your fossil? No. Genus: Rafinesquina Extinct D-shaped brachiopod with a straight hinge at the back. They have compressed shells with fine radial ribs. Rafinesquina lived on the seafloor and was a suspension-feeder. Fossils are abundant in Cincinnati, Ohio. Geologic Range: Ordovician 1) This distinctive shell is described as shaped. 2) Rafinesquina is recognized by its wide, flat shells. How many shells do you see on your fossil? Class: Inarticulata No. Genus: Linguia Brachiopod with valves made of phosphate. The valves do not have a hinge line, opened and closed by muscles. They used their pedicle to burrow in to soft bottom sediments. These brachiopods are suspension-feeders. Geologic Range: Lower Cambrian to Present 1) Is Lingula a good index fossil? yes 2) Do you see a hinge line on your fossil? yes Was this a benthic epifaunal or infaunal brachiopod? B enthine lass: Anticulata intewnal branchiral Genus: Mucrospirifer inct brachiopod with a straight hinge line that extends ward to form a point, giving it a wing-like appearance. " are sometimes called "butterfly shells". Mucrospirifer was a suspension-feeder living on the seafloor. imum diversity in the Devonian. is fossil exhibits prominent curved lines called at features gives it the wing-like "butterfly" appearance? hinge line (growth lines, long hinge line, ribs) this a benthic epifaunal or (infaunal brachiopod? infauth lines, long hinge line, ribs) Genus: Platystrophia rachiopod with large, thick calcite valves. The valves ominent fold and sulcus. Both valves exhibit ribs. hia was a benthic, epifaunal suspension-feeder.
