Palynodinium grallator is a fossil species of dinoflagellate cyst used to demarcate the K/Pg boundary.
Summary
[edit]
| Description |
English: This image was produced by Sandy McLachlan in 2018 at the Paleoenvironmental/Marine Palynology Laboratory, School of Earth and Ocean Sciences, University of Victoria (Victoria, British Columbia, Canada). It illustrates a specimen of the organic-walled dinoflagellate cyst Palynodinium grallator, a fossil species of dinoflagellate cyst used to demarcate the K/Pg boundary. The image was obtained during a survey of organic-walled microfossil material from the Oyster Bay Formation of eastern Vancouver Island. The investigation was part of a study on Late Cretaceous–early Paleogene marine micropaleontology in the eastern North Pacific, which resulted in the first reported K/Pg boundary west of the Rocky Mountains in North America based on biostratigraphic controls (McLachlan and Pospelova 2021). |
