Palynostratigraphy of the Cretaceous-Paleogene mass-extinction interval of the Southern Hemisphere

open access: yes, 2012
The palynofloral changes around the Cretaceous-Paleogene (K-Pg) mass extinction event reveal the fine details of vegetation response to a global environmental crisis-in this case an asteroid impact in Mexico 65.5 million years ago.

High resolution comparative palynostratigraphy and palaeoecology of Oligocene sequences in the terrestrial basins of the Western British Isles and the marine North Sea basin [PDF]

open access: yes, 1996
Oligocene sediments from six terrestrial basins in western Britain and two boreholes from the North Sea Basin were studied. These Oligocene sequences are dominated by claystones with silts, sands, conglomerates and lignites.
