Abstract
The Late Mississippian (359 – 323 my) Pennington Formation represents the final stage of marine carbonate deposition on the southern Cumberland Plateau of Tennessee. The layer marks the last phase of shallow marine sedimentation before deposition of overlying deltaic clastics of the Raccoon Mountain Formation and Warren Point Sandstone. In the Sewanee, Tennessee area the Pennington is composed largely of disarticulated invertebrate fossils typical of a shallow marine assemblage of the time, including pelmatazoans (crinoids and blastoids), bryozoans, brachiopods, foraminifera, and gastropods. In the Depot Branch area of Sewanee over 40 meters of thin-bedded limestones contain an unusually large quantity of shark teeth. Preliminary examination of samples likely record the presence of the genus Saivodus and perhaps members of the genera Agassizodus and Campodus. All teeth occur as isolated fossils
and aid in the characterization of the Late Mississippian ecosystem of the Sewanee area
