This paper describes a rare occurrence of a rich and diverse palynological assemblage from a controversial stratigraphic unit in northwestern Saudi Arabia. The composition of this assemblage strongly suggests a Pridoli age and therefore it is referred her to the Tawil Formation. The assemblage encountered contains very characteristic chitinozoans, acritarchs, tasmanities, scolecodonts and some land-derived miospores and hilate spores. Chitinozoans such as Margachitina elegans, Ancyrochitina fragilis brevis, Ancyrochitina fragilis, Sphaerochitina sphaerocephala, Urnochitina urna, Pseudochlathrochitina carmenchui and Lagenochitina brevicollis confers with the Pridoli age assignment. This assemblage correlates very well with Assemblage D from the Alternances Greso-Argileuses Formation of the A1-61 well in northwestern Libya.
