A review of the angiosperm pollen genus Cretacaeiporites Herngreen, with one new species from the Upper Cretaceous of Egypt

Abstract

An emended diagnosis of the angiosperm pollen genus Cretacaeiporites is proposed to encompass all attributed species. A comprehensive review of all Cretacaeiporites species is also given with the description of C. aegyptiaca sp. nov. from the subsurface mid-Cretaceous (Bahariya Formation) of northwest Egypt. A new combination, C. krutzschi (Boltenhagen) comb. nov., is also proposed. The review includes the original diagnosis of each taxon, holotype line illustrations and remarks on how to differentiate them from each other, in addition to a compilation of their known stratigraphical range and occurrences based on an exhaustive survey of their previous records.

Notes on contributors

Mohamed I.A. Ibrahim

MOHAMED I.A. IBRAHIM is a professor of palynology and applied micropalaeontology in the Department of Environmental Sciences, Faculty of Science, at Alexandria University, Egypt. He has an MSc (1986) in palynology and micropalaeontology from Alexandria University. He obtained his PhD in palynology, micropalaeontology and palaeoenvironment in 1993 from the University of Alexandria and the Technical University of Berlin through a combined channel program. He taught palynology, micropalaeontology and palaeoenvironment from 1993 to 1995 at the Geology Department of Alexandria University, and was a part-time palynostratigraphical consultant for GEOEX-Egypt and GeoComp. Mohamed was seconded to the Geology Department, College of Science, Qatar University from 1996 to mid-2002. He is the author of more than 45 research articles on the palynology, micropalaeontology and palaeoecology of Egypt, Libya, Qatar and Kuwait. He was a member and the National Coordinator of the IGCP 381 ‘South Atlantic Mesozoic Correlation’ and a member of AASP, BMS, GSE, EPS and ESQUA. In 2003, he was awarded the Alexandria University Scientific Prize in Geological Sciences, and in 2004 he was awarded the State of Egypt Prize in Geological Sciences. He has been the Dean of the Faculty of Science, Alexandria University, since 2010.

Mohamed K. Zobaa

MOHAMED K. ZOBAA is an assistant professor at Benha University, Egypt. He is currently on sabbatical, working as a post-doctoral fellow at Missouri University of Science and Technology, USA. Mohamed received a BSc in geology and an MSc in palynology from Benha University. In 2011, He received his PhD from Missouri University of Science and Technology. Mohamed's main interests and expertise include using palynology to understand the accumulation, distribution, and maturation of sedimentary organic matter in time and space, and how they can be employed to characterise hydrocarbon systems, interpret depositional palaeoenvironments, delineate biostratigraphical events and solve geologically related problems. His expertise also includes palynomorph taxonomy and palaeoclimatic reconstructions. Mohamed's past professional appointments include: research assistant at the Nuclear Materials Authority, Egypt; teaching assistant at Benha University; research associate at East Tennessee State University, USA; teaching assistant at Missouri University of Science and Technology; and geoscience intern at ConocoPhillips, USA. Throughout his career Mohamed has received several awards including the Geology and Geophysics Publication Award, Missouri University of Science and Technology; the Best Student Poster Award, AASP-The Palynological Society; the Outstanding Graduate Scholar Award, Missouri University of Science and Technology; and the Dr. Alfred Spreng Research Award from Missouri University of Science and Technology.
