A newly discovered fossil assemblage including trilobite, ostracod, bryozoan, and microcrinoid fragments and agglutinated foraminifers has been found in the Wilhite Formation, Walden Creek Group, Ocoee Supergroup, in the foothills of the Great Smoky Mountains, Tennessee. These fossils prove a Paleozoic age for the Walden Creek Group, which had been interpreted to be of Late Proterozoic age. The foraminiferal assemblage indicaes the Silurian as the older age limit for the Walden Creek Group. These findings make necessary a redefinition of the Ocoee sedimentary basin and reinterpretation of models of the evolution of the Blue Ridge structural province.
