Palynological research • Strother & Taylor (2024) review the early spore fossil record. • Evidence of the presence of robust spore walls sharing similarities with those seen in
embryophytes, but probably not produced in a
sporangium, is reported in spores from the Cambrian strata in
Tennessee by Taylor & Strother (2024). • A study on spore assemblages from Devonian paleosols in Voronezh and adjacent regions (
Russia), interpreted as indicative of late
Eifelian?–early
Givetian age, is published by Wang, Alekseeva & Xu (2024). • Mamontov, McLean & Gavrilova (2024) study the ultrastructure of
Maiaspora concava and
M. panopta, providing evidence of similarities with extant
Gleicheniales, and interpret the origin of the Gleicheniales stem as related to closure of the
Rheic Ocean in the Paleozoic. • El Atfy
et al. (2024) review the fossil record of the spore genus
Vestispora from the Carboniferous of
Gondwana, and describe new fossil material of members of five species belonging to this genus from the
Moscovian-
Gzhelian Dhiffah Formation (
Egypt). • A study on the palynoflora from the Permian Emakwezini Formation (
South Africa) is published by Balarino
et al. (2024), who interpret the studied fossils as providing evidence of the presence of complex forests during the
Guadalupian, with plant diversity greater than indicated by the macrofloral record. • Nhamutole
et al. (2024) describe late Permian and Early Triassic palynological assemblages from the Maniamba Basin (
Mozambique). • A study on the earliest Triassic palynoflora from the Bulgo Sandstone (Australia), providing evidence of the presence of dense vegetation in riparian habitat less than 1 million years after the Permian–Triassic extinction event, is published by Vajda & Kear (2024). • A study on the fossil record of Early Triassic
palynomorphs from the
Vikinghøgda Formation (Svalbard, Norway), providing evidence of a shift from lycophyte-dominated to a gymnosperm-dominated vegetation related to the onset of a cooling episode, is published by Leu
et al. (2024). • A study on the age of the Santa Clara Abajo and the Santa Clara Arriba formations and their palynomorph assemblages, previously inferred to be
Carnian-
Norian in age, is published by Benavente
et al. (2024), who determine an upper
Anisian age for both formations, and interpret their findings as indicating that the taxonomic composition of Triassic
Gondwanan palynomorph assemblages correlates more strongly with latitude than with geologic age. • Description of the late Carnian to early Norian palynological assemblages from the Mungaroo Formation (
Australia) is published by Scibiorski (2024). • The interpretation of
Cycadopites and
Ricciisporites proposed by Vajda
et al. (2023), who considered them to represent, respectively, normal and aberrant pollen produced by the same plant with
Lepidopteris ottonis foliage and
Antevsia zeilleri pollen sacs, is contested by Zavialova (2024); Vajda
et al. (2024) subsequently reaffirm that
Antevsia zeilleri produced
Cycadopites and
Ricciisporites pollen. • Evidence from pollen and spores from the Jiyuan Basin (China), interpreted as indicative of a relationship between two peaks of wildfires of different types and changes in plant communities during the Triassic-Jurassic transition, is presented by Zhang
et al. (2024). • Evidence of high abundances of malformed fern spores from the Lower Saxony Basin (
Germany) during the Triassic–Jurassic transition, interpreted as indicative of persistence of volcanic-induced mercury pollution after the Triassic–Jurassic extinction event, is presented by Bos
et al. (2024). • Rodrigues
et al. (2024) study the palynological assemblages from the Kwanza Basin (
Angola) ranging from the late Albian to the Turonian, reporting the presence of pollen indicative of subtropical to tropical climate and
dinocysts with higher latitude affinities, and interpret these findings as indicative of existence of an open connection between the Central Atlantic and South Atlantic oceans in the mid-Cretaceous. • El Atfy
et al. (2024) study the palynoflora dominated by
Afropollis jardinus from the
Cenomanian Bahariya Formation (
Egypt), and interpret plants producing
A. jardinus as likely parts of tropical, aquatic or mangrove-like vegetation. • Description of the palynological assemblages from the Arlington Archosaur Site (
Woodbine Group;
Texas, United States), interpreted as indicative of tropical to subtropical climatic conditions during the Cenomanian, is published by Lorente, Noto & Flaig (2024). • Evidence from the study of spores and pollen from the maritime Oyster Bay Formation (Vancouver Island, British Columbia, Canada), interpreted as indicative of the presence of
refugia permitting greater stability of terrestrial plant communities during the Cretaceous-Paleogene transition than in continental regions, is presented by Patel
et al. (2024) . • Evidence from fossil pollen assigned to the form genus
Classopollis, interpreted as indicative of existence of a
refugium of members of the family
Cheirolepidiaceae, is reported from the Paleocene Lower
Wilcox Group (
Texas,
United States) by Smith
et al. (2024). • Grímsson
et al. (2024) report the discovery of fossil pollen of members of the genus
Hyaenanche from the Eocene Kipini Formation (
Kenya), representing the earliest record of the genus from Africa. • A study on changes of morphology of grass pollen from South America since the Early Miocene and on its probable drivers is published by Wei
et al. (2024). • Evidence from fossil pollen interpreted as indicative of existence of ecological corridors linking Andean, Atlantic and Amazonian regions of South America during the
Last Glacial Maximum, resulting in establishment of complex connectivity patterns between plants from the studied parts of South America, is presented by Pinaya
et al. (2024). • Evidence from the study of pollen and microcharcoal data, indicative of decline in cold- and moist-affinity vegetation and spread of seasonal tropical vegetation in northern Amazonia during the slowdown of the
Atlantic meridional overturning circulation 18,000 to 14,800 years ago, is presented by Akabane
et al. (2024). ==General Research==
