...Lewis E. Stover Abstract "One new genus and four new species of ephedroid pollen from the Albian-Turonian sequence in the Senegal basin, west Africa, are established. Specimens of the new taxa--Steevesipollenites, n.gen.; S. multilineatus, n.sp. (the type species), S. binodosus, n.sp.; Gnetaceae...

... a predominantly fluvial setting. The frequent occurrence of Palmae pollen indicates warm, humid conditions during the Late Cretaceous, although seasonal or hinterland aridity is suggested because of the occurrence of ephedroid pollen. Late Paleogene and Neogene assemblages are characterized by amorphous organic...

... and Mahmoud, 1998 ). Gymnosperm pollen is dominated by Araucariacites , produced by conifer vegetation developed on the relatively dry hinterland, and associated ephedroids which are commonly interpreted as xerophytes ( Schrank and Mahmoud, 1998 ). The presence of woody debris ( Fig. 3T ) and especially leaf...

A (Lower Cretaceous, Falkland Plateau; Kotova 1983 ) and Balmeiopsis robustus (Lower Cretaceous, Western Australia; Backhouse 1988 ). In the present study it is retained as a separate...

... terrestrial spore and pollen taxa. In addition there are difficulties in applying published taxonomic age ranges to incomplete sections that might be bounded by barren intervals, and without additional stratigraphical control of marine microfossils. It is not always clear how well-constrained age criteria...

... areas near the paleoequator where Araucariaceae and ferns were more common: Doyle et al. 1982 ; Schrank 1990 ; Brenner 1996 ; Doyle 1999 ). The common occurrence of striate ephedroid pollen ( Ephedripites ) is another similarity to Northern Gondwana and putative indicator of aridity, as is the lower...
