A search for dinoflagellates in the upper Paleocene Naheola Formation of Wilcox County, Ala., has disclosed numerous reworked Paleozoic and Mesozoic palynomorphs, including some unsuspected Jurassic and Lower Cretaceous specimens; an attempt is made to relate these to their source sediments. Jurassic and Lower Cretaceous sediments, although known in the subsurface, have not been demonstrated to crop out east of the Mississippi River. The presence of the reworked palynomorphs in the Naheola Formation suggests that sediments of these ages extended to the surface in central Alabama during late Paleocene time and supports the suspicion that an outcrop of undated sediments in central Alabama, the Vick Formation, may be of pre-Tuscaloosa Mesozoic age.
