Defence of bachelor thesis: Surface analysis of fossil leaves

Palaeontology

Wednesday the 8th of November, Magnus Harding will defend his bachelor thesis on the application of chemical surface analyses on fossil leaves.

Surface analysis of fossil leaves is the title of the project, which is being presented and examined on Wednesday the 8th of November at 3 pm at the Geological Museum. Tais W Dahl of the Section of Geobiology and Minerals is the supervisor of the project, and Gunver Krarup Pedersen of the Geological Survey of Denmark and Greenland (GEUS) is the examiner.

The main hypothesis of the project is that it is possible to have pristine organic material preserved during fossilization. A number of different methods for chemical analysis and characterisation of surfaces has therefore been utilized in an attempt to map the chemical distribution of elements across the flattened fossil.

The fossil examined in the project is a 60 million year old conifer branch found in Western Greenland during an expedition in the 1950s.
