...-pollenites diversus n.sp.; and G. clathratus, n.sp.--reveal morphologic features unknown in Recent Ephedra pollen. The described forms, together with associated ephedroid grains very similar to those from extant Ephedra species, attest to the diversity of Cretaceous gnetalean pollen." GeoRef, Copyright...

... 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...

... typical Southern Laurasian Early Cretaceous spore and gymnosperm pollen groups, although not as many as in the Potomac Group, whether due to less favorable climate or less suitable local habitats. Angiosperm pollen, which includes both monosulcate and tricolpate types, makes up about 2% of the terrestrial...

Previous investigations on angiosperm pollen from the Cretaceous Egyptian sediments helped in providing new features in pollen...
