Pennsylvania Corals, Missourian Corals, Fossil Corals
As in Kansas where distinct zonation of corals has been recognized, the dissepimental Rugosa Dibunophyllum, Neokoninckophyllum and Geyerophyllum are invariably associated with limestones and thin calcareous shale interbeds within limestone units. In both states, the nondissepimental rugose genera Lophamplexus and Stereostyllls have been collected from both limestones and thick intervening shale units. The tabulate genera Syringopora and Cladochonus are restricted to limestones in both areas. Although the vertical distribution of Iowa and Kansas dissepimental corals is similar, Iowa rocks contain fewer and generally smaller corals than correlative Kansas units. Elements of the informal dissepimental coral zones 1, 3 and 4 established by Cocke (1970, 1972) in Kansas are presently known in Iowa.
