Nanoxanthiopollenites, a new monolete miospore from the upper pennsylvanian of Kansas

Abstract

Nanoxanthiopollenites mcmurrayi gen. et sp. nov. is described from the Bonner Springs Shale, Zarah Subgroup, Kansas City Group, Missourian Stage, Upper Pennsylvanian Series of Johnson County, Kansas. The new spore genus is monolete, with the suture being somewhat sigmoid in direction; sculpturing of the exine surface consists of conspicuous spinae. The general morphological features indicate a possible relationship to the Medullosaceae.
