Late Mississippian productoid brachiopods Inflatia, Keokukia, and Adairia, Ozark region of Oklahoma and Arkansas

Specimens of the Late Mississippian productoid genera Inflatia and Keokukia from northeastern Oklahoma and northwestern Arkansas, collected from the Boone and “Moorefield” Formations, Hindsville Limestone, and Fayetteville Shale, display morphologic similarities and differences that delineate species and determine their biostratigraphic ranges. Generic assignments are based primarily on internal characters. Systematic descriptions include seven species of Inflatia Muir-Wood and Cooper: Productus inflatus McChesney (the type species), P. cherokeensis Drake, P. clydensis Girty (figured herein for the first time and for which a lectotype is designated), four new species of Inflatia ( I. cooperi, I. gracilis, I. pusilla , and I. ? succincta ), and one species of Keokukia (the type species for the genus, K. sulcata Carter). Also proposed and described is a new genus, Adairia , with its type species Productus ( Marginifera ) adairensis Drake. All these species of Inflatia, Keokukia , and Adairia have biostratigraphically restricted ranges within the Meramecian and Chesterian sequence in the Ozark region.

Significance of the Goniatite Bilinguites eliasi and Associated Biotas, Parkwood Formation and Bangor Limestone, Northwestern Alabama

The Bangor Limestone contains conodonts, smaller calcareous foraminifers, and a sparse marine macrofauna dating it as late or latest Chesterian (Late Mississippian). The Parkwood Formation, a paralic sequence disconformably overlying the Bangor, has yielded a fauna containing the reticuloceratid ammonoid Bilinguites eliasi Manger and Saunders which permits correlation of the Parkwood Formation in north-western Alabama to the upper part of the Prairie Grove Member of the Hale Formation in the type Morrowan sequence. The macrofauna occurring with the ammonoid, supports this correlation. Bilinguites eliasi also alows correlation with the lower part of the Yeadonian Stage (lowest Namurian 'C') of Europe. Florules collected just below and above the goniatite occurrence in Frankling County correlate with those in the lower two-thirds of the New River Formation, southern West Virgina, and with the upper Namurian of western Europe. -from Authors

Chesterian davidsoniacean and orthotetacean brachiopods, Ozark region of Arkansas and Oklahoma

Three species of orthotetaceans and one species of davidsoniacean are among the strophomenid brachiopods from Chesterian (Upper Mississippian) rocks of northern Arkansas and northeastern Oklahoma. Type material from the Fayetteville Shale, Orthotetes subglobosus and O. subglobosus var. protensus, is figured for the first time. We regard these species, and O. subglobosus var. batesvillensis Girty from the Batesville Sandstone, as distinct species, for which we are selecting lectotypes. We describe a fourth species, O. stenopsis n.sp., from the Pitkin Limestone. Another species, described from the Pitkin as Streptorhynchus suspectum, has an impunctate shell and is thus not an orthotetacean. This bizarre species generally has a long twisted beak, high interarea, and large forked cardinal process; a myophragm may occur in either valve, but more commonly is in the brachial valve alone. We designate a lectotype for this species and propose a new genus Adectorhynchus and a new family Adectorhynchidae, under the Davidsoniacea, for this taxon.
