FIGURE 5 in Telychian (Llandovery, Silurian) conodonts from the LaPorte City Formation of eastern Iowa, USA (East-Central Iowa Basin) and their implications for global Telychian conodont biostratigraphic correlation

FIGURE 5. Stratigraphic column and conodont range chart for the LPC in the Garrison Core. Dashed lines indicate uncertainty in range. M = mudstone, W = Wackestone, P = Packstone, F = Floatstone for carbonate lithologies. L.H. = Lower Hopkinton. Log colors represent the color of the rock. Correlation of conodont biozonation to chronostratigraphic units from Cramer et al. (2011).
