| Abstract | Most dinoflagellates are free-living single-celled organisms that inhabit aquatic environments with a mostly organic-walled cyst stage in their life cycle. The evolution of dinoflagellates through their
cyst fossils goes back to Middle Triassic. The intricate Jurassic through Cenozoic organic walled cyst taxonomy allows a refined marine biostratigraphy. |
| Summary | (Plain Language Summary, not published)
Dinoflagellate cysts are a primary tool for biostratigraphic and paleoenvironmental analysis in Mesozoic and Cenozoic rocks, including those of the
Baffin region. This article is an overview for non-experts of these fossils and their living counterparts, written as a "minichapter" for the upcoming revision of the Geological Time Scale book, the international standard reference for stratigraphy.
Dinoflagellates are mainly single-celled organisms that live mostly in marine environments. They have left a fossil record of calcareous and organic-walled cysts. The latter are preserved in palynological (organic-walled microfossil) assemblages
and show a remarkable variety of rapidly evolving morphological types, a property that makes them ideal time-marker species. They can occur in the thousands in individual samples, unlike the macrofossil groups that were used initially to develop the
geological time scale. They are therefore especially valuable in subsurface stratigraphic studies. |
