Palynological assessment of a Pleistocene age locality from southeastern North Carolina, U. S. A.

A recently discovered locality in an open aggregate mine pit owned by the Martin Marietta Corporation near Wilmington, North Carolina (34° 22. 368’ N, 77 ° 50.356’ W), has produced abundant macrofossil remains that show a wide range of diversity. The exact environmental setting is uncertain, but appears to be channel-fill or lacustrine deposit based on the matrix. A palynological assessment of the sediment shows a wide range in diversity. Pollen types found include, but are not limited to Pinus, Taxodiaceous types, Picea, Alnus, Liqudambar, Betula, Quercus, Ilex, Monolete Fern types, Ambrosia spp., and other Compositae. Fungal, diatom, and protozoan palynomorphs are also present, which presents evidence of a wetland or riverine setting. The locality lacks Isoetes spores, which indicates an interglacial period. Little is known of the Pleistocene macrofossil flora of the southeastern United States and few complete interglacial floras of North Carolina. An analysis of this locality adds to our knowledge of this time period in this region.
