Palynological research • Wellman et al. (2026) describe the Devonian spore assemblages from the
Portilla and
Candás formations (Spain), and interpret spores from the latter formation as indicative of presence of a flora dominated by arborescent
archaeopteridaleans and
aneurophytaleans. • Gutiérrez et al. (2026) study the composition of the first palynological assemblage recovered from the Permian (probably Lopingian) strata of the upper member of the La Golondrina Formation (Argentina), providing evidence of presence of a forest dominated by members of Glossopteridales, with undergrowth including ferns, sphenophytes, lycophytes and bryophytes. • Evidence from the study of the palynological record from the Jiyuan Basin in the southern part of the
North China Plate, indicative of four distinct phases of terrestrial vegetation transition across the
Carnian pluvial episode that were temporally linked with indicators of volcanic activity and were accompanied by climate changes, is presented by Zhang et al. (2026). • Sajjadi Hezaveh & Hashemi-Yazdi (2026) reconstruct the composition of the plant assemblage from the Triassic (
Rhaetian) strata of the Qadir Member of the
Nayband Formation (Iran) and the basis of the study of spores and pollen, interpreted as indicative of affinities of the studied flora with both floras from northern Gondwana and with ones from southern Laurasia. • Vilas-Boas et al. (2026) study the composition of Late Triassic and Early Jurassic palynological assemblages from the Algarve and Lusitanian basins (Portugal), providing evidence of overall dominance of xerophytic plants across both basins, as well as evidence of links of studied assemblages with floras from the western
Tethyan margin and North America, and report malformed sporomorphs interpreted as evidence of environmental impact of
Central Atlantic magmatic province activity. • Rosin et al. (2026) study the composition of the palynological assemblages from the Westbury, Lilstock and Redcar Mudstone formations in the Cheshire Basin (United Kingdom), recording changes of composition of vegetation in response to environmental changes during the latest Triassic and Early Jurassic. • A study on spores and pollen grains from the Schandelah-1 core (Germany), providing evidence of increased occurrence of malformed pollen grains and shifts in the composition of the palynofloral assemblage indicative of ecological stress during the
Toarcian hyperthermal event, is published by Galasso, Foster & van de Schootbrugge (2026). • Yang et al. (2026) report evidence from multiproxy analyses (including the study of palynological assemblages) of continental succession from the Junggar Basin (China) indicative of a shift from fern groundcover to conifer canopy during the
Jenkyns Event and of recovery of ferns after the event, as well as indicative of a more humid climate with reduced monsoon seasonality that reduced wildfire activity during the Jenkyns Event. • Evidence from the study of palynological assemblages from the Upper Jurassic strata from the Binalud Mountains (Iran), indicative of increase in the abundance and diversity of warm-adapted cheirolepid conifers over time in response to a regional warming, is presented by Kalanat (2026). • Buratti et al. (2026) study the composition of palynological assemblages from the Gorgo a Cerbara section (Barremian–Aptian transition; Italy), and report evidence of presence of pollen
Afropollis cf. jardinus representing one of the earliest records of flowering plants in the
Tethyan realm. • Zhang et al. (2026) study the composition of palynological assemblages from the Jiufengshan Formation (Dayangshu Basin, China), and report evidence of increase of taxonomic richness of the flowering plants in the studied area during the Aptian. • Carvalho et al. (2026) reconstruct the composition of Aptian assemblages of spore-producing plants from the south Atlantic margin and their responses to environmental changes at the time of the opening of the southern Atlantic Ocean on the basis of the study of palynological assemblages from eight Brazilian sedimentary basins. • Evidence from the study of palynological assemblages from
Codó and
Itapecuru formations, indicative of changes of composition of plant assemblages in northeastern Brazil in response to climate and moisture variability during the late Aptian, is presented by Correia et al. (2026). • Lorente (2026) calculates the biomass of Cenomanian conifers in the eastern North America and the amount of their dispersed pollen on the basis of the study of the fossil record from the Arlington Archosaur Section (
Woodbine Group; Texas, United States) and comparisons with extant conifers. • Evidence from the study of spores, pollen and microcharcoal abundances from Paleogene sediments from a hydrothermal vent crater in the
North Atlantic Igneous Province on the Norwegian Margin and from other mid- and high latitude continental margins, indicative of rapid vegetation and soil disturbances in response to environmental changes at the onset of the
Paleocene–Eocene thermal maximum resulting in widespread appearance of fern-dominated pioneer vegetation across mid- and high-latitude regions of the world, is presented by Nelissen et al. (2026). • Raynaud et al. (2026) reconstruct the composition of the Eocene plant assemblage from the
embrithopod-bearing Bultu-Zile site (Meryemdere Formation; Turkey) on the basis of the study of the freshwater-deposited palynoflora from the site, and interpreted as indicative of a swamp-freshwater environment. • Barreda et al. (2026) study the composition of the palynological assemblage from the Río Pichileufú locality (
Huitrera Formation, Argentina), providing evidence of presence of a middle Eocene flora dominated by gymnosperms and
Nothofagaceae, and including fossil pollen representing the oldest record of the
crown group of
Barnadesioideae reported to date. • Evidence from the study of palynological assemblages from the Miocene El Chacay Formation (Argentina) indicative of increase in floral diversity during the early Burdigalian before the onset of the
Middle Miocene Climatic Optimum is presented by Tapia et al. (2026). • Pound et al. (2026) study the Miocene (Serravallian) palynoflora from the Kenslow Member of the Brassington Formation (United Kingdom), interpreted as fossil record of plant growing in an area with an oceanic type climate with more rainfall during the summer than the winter (but with no pronounced dry season), and report evidence of impact of seasonal changes of availability of moisture on the composition of the studied Miocene forest. • Li et al. (2026) report evidence from the study of the palynological record from the East China Sea continental shelf spanning the past 71,000 years indicative of presence of a cool, dry temperate grassland biome during the lowstand intervals (including the
Last Glacial Maximum), as well as evidence of presence of an open-forest landscape during the milder conditions of the
Marine Isotope Stage 3, and interpret their findings as supporting the interpretation of the exposed East China Sea continental shelf as a habitat facilitating the initial dispersal of early modern humans into East Asia. • Evidence from the study of pollen record from eastern
Nanling Mountains, indicative of impact of climate changes (and, since the late Holocene, human activities) on the composition of vegetation in the studied area during the last 46,000 years, as well as of existence of cool and humid refugia in subtropical China during the Last Glacial Maximum, is presented by Quan et al. (2026). ==General research==
