Tabulate corals and echinoderms from the Pennsylvanian Winterset limestone, Hogshooter formation, Northeastern Oklahoma

The Pennsylvanian Missourian Hogshooter Formation of northeastern Oklahoma locally contains abundant tabulate corals, crinoids, and rare blastoids in calcarenites and calcareous shales. These organisms are most abundant in reef associated beds at a single locality. None were collected from the phylloid algal mound complex which comprises most of the Hogshooter outcrop belt in Oklahoma. Species of four tabulate coral genera are described from reef flank beds. They are Sutherlandia cg. S. irregularis Cocke and Bowsher, 1968, Striatopora kolmani, n. sp., Michelinia adibilus, n. sp., and Cladochonus conus, n. sp. From the same locality the echinoderms Aglaocrinus compactus Moore and Plummer, 1940, Lecythiocrinus graybilli, n. sp., Delocrinus cf. D. verus Moore and Plummer, 1940, Erisocrinus p., Graffhamicrinus p., Paragassizocrinus mcguirei Stimple, 1939, and Agmoblastus dotti (Moore and Strimple, 1942) were recovered. Additional species of crinoids known from two other localities are Erisocrinus cf. E. typus, Sciadiocrinus p., Sciadiocrinus abolitus, n. sp., Ulocrinus buttsi Miller and Gurley, 1890, Laudonocrinus sp. Laudocrinus subsinuatus Moore and Plummer, 1940, and Parerisocrinus obovatus (Moore and Plummer, 1940).
