Changes in terrestrial vegetation during the mid-Cretaceous and their link to climate environmental change are poorly understood. In this study, we use plant macrofossils analysis of fossil pollen spores from Western Desert, Egypt, assess temporal changes communities Cenomanian. The investigated strata have relatively diverse sporomorph assemblages, which reflect nature parent vegetation. Specifically, palynofloras represent ferns, conifers, monosulcate producers, Gnetales, a group...
Abstract The evolution of the present-day African savannah fauna has been substantially influenced by dispersal Eurasian ancestors into Africa. evolved endemically, together with autochthonous taxa, extant Afrotropical clades during last 5 million years. However, it is unclear why moved Here we use sedimentological observations and soluble salt geochemical analyses samples from a sedimentary sequence in Western Iran to develop 10-million-year long proxy record Arabian climate. We identify...
Abstract Palynological investigations of the mid-Cretaceous, delta-influenced Malha Formation and superjacent transgressive Galala exposed at Gebel El Minshera, north Sinai, Egypt, have yielded a sparse but biostratigraphically useful record spores, pollen, rare dinoflagellate cysts. A representative pollen genus Tricolporites, recovered 18 m above base Formation, is post-Aptian in age. An interval comprising upper lower dated as middle Albian/middle Cenomanian based on occurrence...
ABSTRACT Palynological results of a detailed study carried out on 56 samples retrieved from two selected wells (GH 404-2A and SA-E6A) the Hilal Shoab Ali fields within southern part Gulf Suez, Egypt, are presented. This is mainly focused poorly dated Nukhul Formation, for which very little information palynology available despite its importance petroleum viewpoint. The assemblages discovered in our moderately preserved reveal sparse but significant record spores pollen dinoflagellates...
The Upper Cretaceous (early Cenomanian) Bahariya Formation of Egypt has an outstanding reputation for its wealth vertebrate remains, including a variety iconic dinosaurs, like the carnivorous Spinosaurus and Carcharodontosaurus, as well herbivorous Aegyptosaurus Paralititan. Besides these dinosaur fossils, yielded also invertebrate plant but even today many aspects concerning continental palaeoenvironments reflected in deposits (including occurrence palaeo-wildfires) have not been studied...
Abstract. Moderately to well-preserved palynomorph assemblages were recorded from thirty samples of the Nukhul Formation (GH 404-2A Well), southern Gulf Suez, Egypt. The taxa are dominated by highly diverse fungi, freshwater algae (e.g. Botryococcus, Pediastrum) beside a sparse record spores and pollen. Marine palynomorphs, such as dinoflagellate cysts (dinocysts), very rare. stratigraphy age is debated due lack diagnostic fossils foraminifera, nannoplankton). It has been referred mostly...
The fossil record contains abundant evidence for the activity of microorganisms in form characteristic decay structures within plant remains. Despite an abundance charcoal many sedimentary environments, there is little published such from pre-Quaternary clastic deposits. present contribution presents some examples sediments which exhibit pre-charring structures, stratigraphically reaching Permian up to Oligocene. Examples include specimens affected by principle types wood rot known modern...
The palynological investigation of 30 outcrop samples from seven sites in and near the Qattara Depression, north Western Desert, Egypt, has yielded six three containing poorly to well-preserved assemblages including dinoflagellate cysts, freshwater algae, acritarchs, pollen spores. have not been dated previously, but cyst evidence reveals an early or middle Rupelian (Early Oligocene) age for one sample (overlapping ranges Tuberculodinium vancampoae Phthanoperidinium comatum) older...

Oil were analysed for bulk (°API gravity δ properties elemental (sulphur, nickel vanadium) contents. Molecular compositions using liquid gas chromatography, quantitative...
Micropaleontology can give important insights into the provenance and paleoenvironmental conditions in terrestrial sedimentary archives. For current study, 84 samples representing a 2.6 km thick profile from SimplyFolded Zagros Mountain Belt were investigated. They span ca. 10.2 my late Middle Miocene (Serravallian) to earliest Pleistocene (Gelasian), comprised floodplain sediments saline mudstones with an aeolian contribution. The revealed unique Cretaceous radiolarian assemblage comprising...
Abstract Afropollis is a common element in Cretaceous low‐latitude palynofloras ranging from the Barremian to Cenomanian. Despite an abundant fossil record, its affinities are still elusive. Nine ‐rich subsurface samples Cenomanian Bahariya Formation northern part of Western Desert Egypt were palynologically analysed, and palynoflora was compared with previously published material. The geographical distribution ‐yielding strata known macrofloras. material yielded distinct palynomorph...
