Project description
Fossil phyllocarids are among the most intriguing crustaceans in the geological record—delicate, bivalved arthropods whose remains offer rare glimpses into the chemistry of that constructed their exoskeletons. Although their external morphology has long attracted attention, the chemical composition of their fossils remains far less explored, despite its enormous potential to reveal how these organisms lived, died, and were preserved. Their exoskeletons, originally composed of organic and mineral components, can undergo chemical shifts during fossilisation, incorporating elements from surrounding sediments and fluids. As a result, fossil phyllocarids provide a powerful but underutilised system for investigating pathways of preservation, from exceptional soft-tissue retention to diagenetic alteration. This project will draw on material housed within the Geological Survey of New South Wales, offering access to historically significant and well-contextualised specimens. The student (Honours or Masters) will apply techniques such as electron microscopy to map elemental variation and assess how original biological signals have been modified through time. Outcomes will advance our understanding of arthropod fossilisation and help refine how chemical signatures can be used to reconstruct ancient marine environments.
Note: You need to register interest in projects from different supervisors (not a number of projects with the one supervisor).
You must also contact each supervisor directly to discuss both the project details and your suitability to undertake the project.
