OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Dr Julia Gravendyck is a lecturer in systematic botany at the University of Bonn.
The history of plants is preserved not only in leaves and wood, but also in microscopic fossils such as pollen and spores. Abundant across geological time, these microfossils provide a powerful lens for reconstructing vegetation change and evolutionary transitions. Julia’s lecture explores how they refine our understanding of plant evolution, from the earliest land plants to the rise of flowers. Recent discoveries of Early Cretaceous pollen shed new light on Darwin’s “abominable mystery” of angiosperm origins, while palynology also reveals how plant communities responded to mass extinctions. Together, these insights show how tiny fossils illuminate some of the biggest questions in botany: how plant communities coped with global crises, and where flowering plants first transformed Earth’s ecosystems.
