<abstract><title style='display:none'>Abstract</title>The current study presents a fully qualitative palynological investigation carried out on the Raha Formation encountered from three wells in the Bakr Oil Field of the Gulf of Suez, Egypt. Around 30 species of pteridophytic spores, 26 species of angiosperm pollen, 24 species of gymnosperm pollen and 27 species of dinoflagellate cysts have been recorded. However, achritarchs, microforaminiferal test linings and freshwater algae are impoverished and sparsely documented throughout the Raha Formation. Two palynozones have been identified based on some stratigraphically significant pollen and spores, arranged from youngest to oldest: (1) Palynozone I (Classopollis brasiliensis–Tricolpites sagax Assemblage Zone) of late Cenomanian age; (2) Palynozone II (Afropollis jardinus–Crybelosporites pannuceus Assemblage Zone) of early-middle Cenomanian age. The distribution and ecological affiliation of specific palynomorph species, as well as various palynofacies parameters, are interpreted. A shallow marine environment from supratidal to distal inner neritic under proximal suboxic–anoxic to dysoxic–anoxic shelf conditions is reconstructed. Palaeobiogeographically, the absence of elaters from the recovered taxa is interpreted in terms of minor floral variation. This may be attributed to climatic and/or an environment-controlled niche establishment, which possibly was shaped by the existence of a physical barrier hindering the distribution of such type of elaterate parent plants.</abstract>

AUSTRIAN JOURNAL OF EARTH SCIENCES is the official journal of the Austrian Geological (ÖGG), Mineralogical (ÖMG), Palaeontological (ÖPG) and Hydrogeological (ÖVH) Societies, hosted by a country that is famous for its spectacular mountains, sedimentary basins and classical fossil sites that were and are the birthplace for many geoscientific concepts in modern Earth science. Further information on the journal may also be obtained from the local website at: <A href="http://www.ajes.at/">www.ajes.at</A> AUSTRIAN JOURNAL OF EARTH SCIENCE focuses on all aspects relevant to the geosciences of the Alps, Bohemian Massif and surrounding sedimentary basins. As such, we invite contributions from the fields of mineralogy, geology, geophysics, petrology or hydrogeology, as well as all aspects of palaeontology, palaeobiogeography and biostratigraphy that are of relevance to the greater Alpine region. Contributions on other regions are welcome if they embed their findings into a conceptual framework that relates the contribution to Alpine-type orogens and Alpine regions in general and are thus relevant to an international audience. Contributions are subject to peer review and editorial control according to SCI guidelines to ensure that the required standard of scientific excellence is maintained AUSTRIAN JOURNAL OF EARTH SCIENCES is a peer reviewed journal. Why subscribe and read The journal of the Austrian Geological Society is published for more than 100 years, starting in 1908 as ‘Mitteilungen der Geologischen Gesellschaft in Wien’. Traditionally, the main focus of the journal is on Alpine and Austrian geology and applied geosciences but contributions to all aspects of Earth Sciences are welcome. Austrian Journal of Earth Sciences is an Open Access Journal hosted as of 2018 by SCIENDO.
