| Abstract/Notes | AbstractA new crinoid association reported from the Kope Formation (Katian, Ordovician) of northern Kentucky and southwestern Ohio changes the model for facies distribution of crinoids along an Ordovician onshore-offshore depth gradient. Glyptocrinus nodosus n. sp., Plicodendrocrinus casei (Meek, 1871), Cincinnaticrinus varibrachialis (Warn and Strimple, 1977), and Ectenocrinus simplex (Hall, 1847) are reported from a suspension-feeding assemblage with 26 taxa. This assemblage developed above an argillaceous packstone with most of the fossils preserved in shale. The fauna was comprised principally of secondary epifaunally tiered suspension feeders, deposit feeders, and predators. This is the first reported occurrence of Glyptocrinus Hall, 1847 and Plicodendrocrinus Brower, 1995 from the Kope Formation (lower Cincinnatian), and Glyptocrinus is represented by a new species, G. nodosus. Also, this is the first report of pinnulate camerate crinoids from the deep-water facies of the Kope Formation. Thus, deep-water Cincinnatian crinoid assemblages were comprised of disparids, cladids, and camerates; and the assemblage was characterized by a variety of filtration fan types for acquisition of resources. |
