(Paleozoic Era; Pennsylvanian System by J.M Jewett, H.G. O'Connor, and D.E. Zeller, p. 37.) Avoca Limestone Member of Lecompton Limestone of Shawnee Group. In Kansas, a dark bluish-gray, somewhat earthy limestone occurring in one or more beds. Large fusulinids are the most common fossils. In southeastern Kansas CRYPTOZOON-bearing limestone is characteristic of the member. Algal-molluscan limestone beds occur at the top of the Avoca in some outcrops. The thickness ranges from about 1 to 20 feet. Occurs above King Hill Shale Member of Lecompton Limestone and below Tecumseh Shale. Age is Pennsylvanian (Virgilian).

Thickness 3 to 5 feet in southern Holt County and is of comparable thickness elsewhere in northwestern Missouri. Occurs above King Hill Shale Member of Lecompton Formation and below Tecumseh Shale, both of Shawnee Group. Fossils (fusulinids). Age is Late Pennsylvanian (Virgilian).
