The Jurassic of North-East Greenland: Jurassic dinoflagellate cysts from Hochstetter Forland, North-East Greenland [PDF]

Geological Survey of Denmark and Greenland Bulletin, 2004
Three sections in Hochstetter Forland, North-East Greenland, referred to the Jurassic Payer Dal and Bernbjerg Formations, have been analysed for dinoflagellate cysts.

From hystrichospheres to dinoflagellate cysts: Scandinavian contributions to Evitt’s pivotal recognition of fossil dinoflagellate cysts [PDF]

Palynology, 2020
As one of the remaining living links with two early Scandinavian researchers, the author examines their contribution to Bill Evitt’s breakthrough that launched the development of fossil dinoflagellate cysts into palynology. Evitt, in the early 1960s, revealed that many fossil hystrichospheres were in fact dinoflagellate cysts.

Evidence for Submarine Landslides at Climate Transitions in a High Arctic Fjord (Grise Fiord, Nunavut)

Earth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.
Seafloor mapping in a high Arctic fjord (Grise Fiord) revealed many submarine landslides triggered by iceberg groundings, coastal debris flows and delta collapses. The dating of three of them suggests that they occurred at past climate transitions. ABSTRACT Arctic fjords are experiencing rapid environmental change driven by amplified high‐latitude ...

Dinoflagellate cysts production, excystment and transport in the upwelling off Cape Blanc (NW Africa)

Frontiers in Marine Science, 2022
To extend the understanding of dinoflagellate cysts production, excystment and vertical/lateral transport in the water column, we compared upper water cyst export production with cysts associations and concentrations in the subsurface nepheloid layer ...

Life After Impact: Paleobathymetric Gradients in Post‐K/Pg Nannoplankton Boom‐Bust Successions

Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract The Cretaceous/Paleogene (K/Pg) bolide impact ∼66 Ma caused the near‐demise of calcareous nannoplankton–key primary producers and major components of the biological pump that exports organic and inorganic carbon to the deep sea. Despite their ecological significance, resolving the exact impact of nannoplankton's mass extinction on ecosystem ...

Biogeochemical, sedimentological and dinoflagellate‐based reconstruction of the Holocene palaeoenvironment of the east Limfjord, Denmark

Boreas, Volume 55, Issue 4, Page 1055-1072, October 2026.
To assess how the eastern part of the Limfjord system has changed over the Holocene, relative to the wider Limfjord and western Baltic region, a sedimentary succession spanning c. 9600–150 cal. a BP was collected from Nibe Bredning, near Sebbersund, from a shallow coastal inlet along the eastern connection between the Limfjord and the Kattegat (north ...

Sedimentary Environmental Evolution of the Western Taiwan Shoal Area since the Late Pleistocene

Journal of Marine Science and Engineering, 2021
A new pollen analysis and major and trace element contents were conducted on a 40 m long gravity core recovered from the Taiwan Shoal (sand ridges), south of the Taiwan Strait, beginning in the Late Pleistocene.

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

Journal of Petroleum Geology, Volume 49, Issue 4, Page 1179-1194, October 2026.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

Paleocene – Late Oligocene dinoflagellate cysts biostratigraphy, onshore Niger Delta

Geosystems and Geoenvironment
A new biostratigraphic biozonation for the Paleocene to Late Oligocene succession of the onshore Niger Delta has been developed based on the identification of significant stratigraphic dinoflagellate cyst events.
