Nonmarine Cretaceous palynology of northern Kordofan, Sudan, with notes on fossil Salviniales (water ferns)

, : Nonmarine Cretaceous palynology of northern Kordofan, Sudan, with notes on fossil Salviniales (water ferns). Geologische Rundschau 83(4): 773-786

A palynological investigation of 164 samples from 18 water wells in northern Kordofan, Sudan, enabled the recognition of five informal zones based on pollen and spore assemblages ranging in age from Albian to Maastrichtian. The youngest (late Campanian-Maastrichtian) assemblages are restricted to the Bagbag Basin, whereas Albian-Cenomanian (to Turonian) sediments are widespread to the east and west of the Bagbag area. Impressions of Salvinia floating leaves from outcrops of the upper Hamrat el Wuz Formation, western part of the study area, are among the oldest occurrences of this water fern and indicate a Campanian-Maastrichtian age for these sediments.
