Calcareous dinoflagellate blooms during the Late Cretaceous ‘greenhouse’ world—a case study from western Ukraine [PDF]
PeerJ, 2023 The Late Cretaceous was a unique period in the history of the Earth characterized by elevated sea levels, reduced land area, and significantly high concentrations of atmospheric CO2 resulting in increased temperatures across the globe—a ‘Greenhouse World’

An improved method for the molecular identification of single dinoflagellate cysts [PDF]
PeerJ, 2017 Background Dinoflagellate cysts (i.e., dinocysts) are biologically and ecologically important as they can help dinoflagellate species survive harsh environments, facilitate their dispersal and serve as seeds for harmful algal blooms.

Early Aptian marine incursions in the interior of northeastern Brazil following the Gondwana breakup [PDF]
Scientific Reports, 2023 This study reports a set of primeval marine incursions identified in two drill cores, 1PS-06-CE, and 1PS-10-CE, which recovered the Barbalha Formation, Araripe Basin, Brazil.

Palynological data of cores MSM5/5–712–2 and PS2863/1–2 from northeastern Fram Strait spanning the last glacial maximum to present [PDF]
Data in Brief, 2019 The palynogical data of two sites from northeastern Fram Strait (MSM5/5–712 and PS2863) encompassing the last 23,000 years are presented here. The data set first includes the palynomorph concentrations: dinocysts (cysts/g) and their fluxes (cysts/cm2/yr)

Biostratigraphic significance of calcareous dinocysts in the Tithonian of the Pieniny Klippen Belt (southern Poland) [PDF]
PeerJBiostratigraphic studies of pelagic Tithonian limestones in the Western Tethys are important for regional palaeoenvironmental reconstructions, particularly for determining the onset of the accumulation of Maiolica-type sediments which dominated Early ...

Where should we draw the lines between dinocyst “species”? Morphological continua in Black Sea dinocysts [PDF]
Journal of Micropalaeontology, 2019 The morphology of dinoflagellate cysts (dinocysts) is related not only to the genetics of the motile dinoflagellate from which it derives, but is also dependent on a range of environmental factors including salinity, temperature and nutrient status ...

Early Oligocene dinocysts as a tool for palaeoenvironment reconstruction and stratigraphical framework – a case study from a North Sea well [PDF]
Journal of Micropalaeontology, 2019 The lower Oligocene (Rupelian) successions are climate record archives of the early icehouse world in the Cenozoic. Even though the number of studies focussing on the generally cold Oligocene is increasing, little is known about climatic variations in ...
