Raman spectroscopy analysis of a thin slice of microfossils contained in rocks from the Draken formation, to the northeast of the island of Spitsbergen in Svalbard. This formation dates back more than 800 million years. The rock analysed is part of the Molecular Biophysics Centre (CBM) rock collection, a unique collection of terrestrial rocks and minerals, some dating back several billion years.
