First Time

Fusulinids from the Howe Limestone Member (upper part of the Red Eagle Limestone, lower part of the Council Grove Group) are described here for the first time. The Howe fauna is particularly significant because it represents the earliest fusulinids known to occur above the new conodont-based Carboniferous (Pennsylvanian)-Permian boundary at the Glenrock Limestone Member-Bennett Shale Member contact (Red Eagle Limestone) in northeastern Kansas. The Howe fusulinid assemblage is composed entirely of species of the genus Leptotriticites. The species L. hughesensis and L. glenensis were originally described from just beneath the new systemic boundary horizon in the Hughes Creek Shale Member and Glenrock Limestone Member, respectively. L. wetherensis is a species from the Stockwether Limestone Member of north-central Texas, which is thought to directly overlie the new systemic boundary in that region. L. gracilitatus is a species reported from below and above the boundary in west Texas and New Mexico. Therefore, the Howe Limestone Member fusulinid fauna is quite transitional in character. The first typical and diagnostic early Permian (Wolfcampian Series) fusulinids in the midcontinent section appear in steps through the stratigraphically higher Neva Limestone Member of the Grenola Limestone (Paraschwagerina kansasensis), and the Cottonwood and Morrill Limestone Members of the overlying Beattie Limestone (Schwagerina jewetti, S. vervillei). This offset of conodont and fusulinid faunal changes should be taken into account in regional and interregional biostratigraphic correlations of the new systemic boundary.

Early Permian (late Leonardian Series) plant assemblages from King, Knox, and Stonewall Counties of North-Central Texas are dominated by seed plants, some apparently congeneric with taxa heretofore known only from the Late Permian or the Mesozoic. Conifers are the dominant elements, including one or more species of Ullmannia, Pseudovoltzia liebeana, both known from the Late Permian Zechstein flora of Germany and England, Podozamites sp., characteristic of the Mesozoic, and Walchia sp., abundant in Early Permian floras. Locally common are Taeniopteris cf. eckardtii, a Zechstein species, an unidentified plant represented by pinnulelike laminae with fine parallel veins, similar to pinnules of some Mesozoic cycads, and calamite stems. Rarely encountered are leaf fragments of the Paleozoic ginkgophyte Dicranophyllum, flabellate ginkgophyte leaves, leaves with a broad midvein and narrow, fimbriate lamina, and Wattia, typical of the Early Permian. Associated with these foliar remains are ovulate reproductive structures including the presumed cycad megasporophyll Dioonitocarpidium, known only from the Mesozoic, a voltzialean cone scale similar to Swedenborgia, and a variety of seeds, some remarkably similar to Agathis, of Cretaceous age. The assemblage includes only rare scraps of foliage and seeds possibly attributable to the pteridophyllous elements (gigantopterids, callipterids, and ferns) that dominate the Permian. The fossil plants occur in multistorey, fining-upwards, tidal-channel deposits that also include pelecypods and fragmentary palaeoniscoid fish. The occurrence of derived lineages in xeric habitats during the Early Permian indicates that some supposed Mesozoic groups actually preceded and survived the end-Permian extinction, reappearing in basinal lowlands during the mid-Mesozoic.
