• While these radiometric dating measurements place the Boltysh crater hundreds of thousands of years after the Chicxulub crater, a 2010 radiometric and palynological study of fern spore (fern spikes) abundance suggested the Boltysh impact may have occurred several thousand years before Chicxulub.
• These specimens include 50,000 overall slabs and plant macrofossils that are categorized as single taxon specimens, or taxa, on slabs, over 50,000 palynological slides and residues, over 18,500 coal ball peels (free and mounted on microscope slides), over 5,000 kg of cut and uncut coal balls, over 8,300 ostracods in micromounts, over 3,000 unprocessed reserves, over 3,400 minerals, rocks and meteorites, including the Keyes Meteorite, and 550 herbarium sheets containing modern plants from which a pollen reference collection has been made.
• These include calcareous microfossils, such as Nannoconus, calpionellids, ammonites, palynological data and magnetostratigraphy, notably magnetozone M19n.
• At present the biostratigraphic information collected is not sufficient to establish a stratigraphical sequence based on palynological and paleontological data.
• Based on stratigraphic position, lithostratigraphic and biostratigraphic correlations, palynological analyses, and other means of geological dating, the Beaufort Group rocks are considered to range between Middle Permian (Wordian) to Early Triassic (Anisian) in age.
• This approach combined ecological, namely phytogeographical and paleobotanic (including palynological) data together with linguistic (phytonymic and comparative) considerations: the distribution of various tree species in Siberia and Eastern Europe (changing over time) was matched against the distribution of the respective tree-names in various Uralic languages (filtered with comparative methods, so that only names of Proto-Uralic relevance be taken into account).
• It has a specific palynological profile of "secondary anthropogenic indicators;" that is, not pollen of cultivated plants but of other species growing on cultivated land: certain percentages of Plantago lanceolata, Sanguisorba minor, Pistacia, Platanus, Quercus calliprinos and Juniperus.
• These estimates are based on means of geological dating including stratigraphic position, lithostratigraphic and biostratigraphic correlations, and palynological analyses.
• Phytoclasts are microscopic plant fragments present in the fossil record, usually found in palynological preparations and acid macerations, and include banded tubes and various nematophytes.
• Palaeoecology of the Bright Angel Shale in the eastern Grand Canyon, Arizona, USA, incorporating sedimentological, ichnological and palynological data.
• Based on palynological and archaeozoological data, the diet mainly consisted of einkorn wheat, barley and bromus, cattle, sheep, pigs and goats.
• There abundant Fossils of microorganisms, as members of the group Archea and other who take advantage of the hydrothermal activity The Acuatic fauna, dominated by invertebrates, includes a diversity of species complete enough to establish Trophic chains: there are traces of feeding, including a coprolite of uncertain affinity with a fish scale, conchostracan valves with traces of possible biotic borings and palynological residues linked with Ostracodan valves.
• Another very important source of data is palynological analysis of a coal-bearing horizon (lignite) interlayered with alluvial fan deposits at the northern border of the Itaboraí Basin, suggesting a Paleocene to Eocene age.
• With both, the palynological and sedimentological study of all available exposures and cores from the Lower–Middle Jurassic shows that the Hasle Formation (Lower–Middle Pliensbachian) is covered by a succession referable to both the Levka and Sorthat beds, which are composed mostly by bioturbated sands, heteroliths and clays along with abundant coal veins, and contain relatively diverse brackish to marine dinoflagellate assemblages that are indicative of upper Pliensbachian, Toarcian and possibly lower Aalenian strata.
