Research
1. Phanerozoic Mass-extinction events; Palynology,
geochemistry and sedimentology of the Cretaceous-Paleogene (K-T) boundary with focus
on extinction
and recovery of vegetation.
Research aims
to determine the rate of turnover (extinction and recovery) of plants at the
Cretaceous-Paleogene event. Investigations focus on sediments from New
Zealand mainland,
Campbell
Island, , Bolivia
and Denmark.
High resolution micropaleontology provides a temporal framework for the
evolution of new species. Analogies with modern plants and ecosystems provide
an important tool for interpreting the fossil record.
The micropaleontological results are placed
in a broader context by sedimentological, geochemical, X-ray
diffraction and Mössbauer spectroscopy investigations on the same
sediments. The extinction at the Cretaceous-Paleogene boundary provides a tool
to interpret other less well resolved mass-extinction events, such as the
Permian- Triassic and Triassic-Jurassic events.
2. Identifying and correlating global Jurassic
events
This
project aims to correlate major Jurassic biological events in marine and terrestrial
sequences, linking Southern and Northern Hemispheres. Project will focus on floristic turnover and
recovery patterns using palynological results from the extensively studied
Cretaceous-Paleogene boundary for
comparison and as a methodological key.
Study
aims to integrate published data from different micropalaeontological fields
but also analyse new palynological and geochemical data from Sweden, New Zealand
and Australia.
