Some Late Pennsylvanian (Virgilian) crinoids from southeastern Nebraska and southwestern Iowa


Some Late Pennsylvanian (Virgilian) crinoids from southeastern Nebraska and southwestern Iowa



Proceedings of the Iowa Academy of Science 871: 1-19



Virgilian age rocks of Iowa and Nebraska contain important crinoid faunas and current collections help to establish distributions and tentative ranges of numerous species. A middle limestone-core shale fauna from the Cass Formation of Nebraska provides small, usually inornate species with close Missourian affinities. Other crinoids studied are from outside shales and upper limestones of the cyclothem and these are usually large, ornate species. Biserial arms are reported for the 1st time for Sublobalocrinus Knapp. The 1st report of flexible crinoids from Virgilian strata of the Iowa-Nebraska area is made here. Current collections of crinoids contain 40 spp. and 31 genera representing 19 families: new species or subspecies are; Isoallagecrinus bassleri intermedius, Graffhamierinus gratesquus, Arrectocrinus iowensis, Pyndoxocrinus inornatus, Sublobacrinus kaseri, Contocrinus invaginatus, Apographiocrinus platybasis. The species Aesiocrinus luxuris is referred to the genus Moundocrinus.
