Exceptional Preservation of Fossils

ARC Laureate Fellowship Project

 

Interpreting the molecular record in extraordinarily preserved fossils: An unexplored archive of Earth’s environment over geological time

This Laureate project aims to unlock an untapped record of our planet’s past, by analysing fossils for new evidence of natural products, in the form of preserved biochemicals or their recognisable degradation products (biomarkers). The well-studied inorganic fossil record has provided a framework for understanding major events in the evolution of life and our planet. However, the proposed project aims to significantly advance current perceptions, by accessing the parallel but rarer organic record of ancient organisms entombed and exceptionally preserved in concretion fossils. Determination of the mechanics and controls of the rapid biofilm entrapment of these organic remains will also contribute valuable new information about geobiological functionality. Expected outcomes from an extension of the fossilised biomarker record are a new way for interpreting our planet’s past, with improved understanding of extinction, environmental change and consequent adaptation.
