Dinoflagellates, their cysts and Quaternary stratigraphy [PDF]
New Phytologist, 1988 summaryDinoflagellates are described, with particular emphasis on their feeding strategies and role within the phytoplankton. The potential ecological value of the fossilizable hypnozygotic cyst in reconstructing the climate throughout the Quaternary marine record is noted.

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.

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman
Journal of Petroleum Geology, EarlyView.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.
