Ecological response to collapse of the biological pump following the mass extinction at the Cretaceous–Paleogene boundary [PDF]
Biogeosciences, 2017 It is commonly accepted that the mass extinction associated with the Cretaceous–Paleogene (K–Pg) boundary (∼ 66 Ma) is related to the environmental effects of a large extraterrestrial impact.

A review of the ecological affinities of marine organic microfossils from a Holocene record offshore of Adélie Land (East Antarctica) [PDF]
Journal of Micropalaeontology, 2018 Integrated Ocean Drilling Program (IODP) Expedition 318 recovered a ∼ 170 m long Holocene organic-rich sedimentary sequence at Site U1357. Located within the narrow but deep Adélie Basin close to the Antarctic margin, the site accumulated ...

The onset of grasses in the Amazon drainage basin, evidence from the fossil record [PDF]
, 2020 Poaceae (the grass family) originated in the Cretaceous, but first dominate the palynological records of the Amazon drainage basin (ADB) in the Neogene (23 to 2.5 million years ago (Ma)).

Progress in palynology of the Gelasian–Calabrian Stages in Europe: Ten messages [PDF]
, 2007 Europe has at present the most extensive network of palynological sites covering the Late Pliocene and the Early Pleistocene or roughly the Gelasian-Calabrian Stages. This paper covers ten points of recent progress in the palynology of this time period:

Islandinium pacificum sp. nov., a new dinoflagellate cyst from the upper Quaternary of the northeast Pacific [PDF]
, 2020 Round brown process-bearing cysts (RBPC) produced by dinoflagellates (Dinophyceae) occur as an important part of assemblage diversities in seafloor sediments worldwide. Here a new species, Islandinium pacificum, is described from surface sediment samples

On the taxonomic resolution of pollen and spore records of Earth’s vegetation [PDF]
, 2014 Premise of research. Pollen and spores (sporomorphs) are a valuable record of plant life and have provided information on subjects ranging from the nature and timing of evolutionary events to the relationship between vegetation and climate.

A high-resolution late Paleocene–early Eocene organic-walled dinoflagellate cyst zonation of the United States Atlantic Coastal Plain [PDF]
Journal of MicropalaeontologyOver the past decades, many expanded sedimentary records from the US Atlantic Coastal Plain (ACP) have been studied in detail to assess causes and consequences of the Paleocene–Eocene Thermal Maximum (PETM; ∼ 56 Ma).
