Summary:
Pg. 284-285, 286, 288-289 (fig. 1), 297-300. Kawvian series (Kawvian epoch). Analysis of physical characters and paleontological features of Pennsylvanian rocks in North America leads to conclusion that stratigraphic cleavage at two positions within system has paramount significance. Three series recognized: Ardian -Lower Pennsylvanian, Oklan -Middle Pennsylvanian, and Kawvian -Upper Pennsylvanian. Approximately upper one-third of Pennsylvanian system belongs to Kawvian series which includes formations from oldest Missourian to base of Permian. Kawvian rocks divided into Missourian stage below and Virgilian stage above. Time equivalent is Kawvian epoch.
Typically developed in valley of Kaw (Kansas) River in northeastern Kansas. Named from commonly used alternative designation of Kansas (or Kaw) River which joins the Missouri at Kansas City.
