 | | Large colonial corals assignable to Tetradium and Favistina are common in the Dillsboro-Saluda transition, and define a widespread coralline zone that is recognizable in many exposures situated between northern Franklin County, Indiana, and western Marion County, Kentucky. |
 | | In the southeastern Indiana outcrop, the coralline zone lies at the top of an interval of highly fossiliferous thin shales and limestones of the Dillsboro Formation that denote an open-shelf environment which was disrupted occasionally by high-energy events that created the shelly limestone beds. |
 | | From Brookville, Indiana, southward to Versailles, Indiana, the coralline zone is dominated by Tetradium, which have diameters as great as 0.45 m (1 ft) and are commonly overturned. |
