Q. â¢^ t Q. e SOUTHERN ILLINOIS AND SOUTHEASTERN MISSOURI Text-figure 8. âComposite stratigraphic sections showing uppermost Ordovician (Gamachian) and lowermost Silurian (Llandovery) units and distnbution of colonial corals in the east-central United States (see Text-fig. lA, foldout inside fi-ont cover). Thicknesses of units are not to scale. Range lines of species (solid for Tabulala, dotted for Rugosa) indicate presence within, but not necessarily throughout, the intervals indicated (for details, see Text-figs. 2-7 and text). Strata containing colonial corals of the Edgewood Assemblage are stippled; colonial corals in overlying strata represent the Silurian assemblage. Hachures indicate the Platymerella manniensis Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Paleontological Research Institution (Ithaca, N.
