The experimental effects of wave processes on arthropod taphonomy: implications for Lagerstätten and Small Carbonaceous Fossils
Funded PhD Project (UK and EU students only)
School of the Environment, Geography and Geosciences
23 February 2020
The bursary is available to UK and EU students only and covers tuition fees and an annual maintenance grant of £15,009 (UKRI 2019/20 rate) for three years. Bursary recipients will also receive up to £1,500 per year for research project costs, as well as office space and computing facilities.
The work on this project will involve:
- Experimental palaeontology and fluid dynamics
- Scanning Electron Microscopy
- Hypothesis testing and statistical analysis
Arthropods are one of most speciose groups of animals on Earth, having undergone a series of diversification events and successfully colonised the marine, freshwater, terrestrial and aerial realms. It is therefore important to understand how the group has reached its present-day biodiversity and the potential biasing factors that might be affecting what is preserved in the fossil record both as a whole and in terms of the composition of individual assemblages and their reflections of communities.
Terrestrial arthropods are frequently preserved in the deposits of lakes; whereas much of what we know about the early evolution of marine arthropods comes from deep-marine Cambrian-aged sites of exceptional preservation. Complementary to this, a record of fragmentary microfossils known as small carbonaceous fossils has been recognized increasingly over the last decade. These are preserved in shallow marine shelf deposits and provide evidence of previously cryptic biodiversity at the time and from different palaeoenvironments.
Actualistic experiments provide one of the best ways to study the likelihood of certain organisms being fossilized, and therefore any biasing factors that might be having an effect. Experiments have tended to focus on the pathways of decay and mineralisation once a carcass has been incorporated into the sediment; whereas the effects of hydrodynamic processes and the transport of organisms to their final resting place has received much less attention.
This project aims to answer questions on the action of wave processes on preservation potential in shallow water lacustrine and marine environments. It will integrate experimental taphonomy and hydrodynamics by using wave-generating flume tanks to replicate shallow water environments and test hypotheses on the effects of wave action and sediment movement on the decay, disarticulation and patterns of microwear for a variety of analogue terrestrial and marine arthropods.
You'll need an upper second class honours degree from an internationally recognised university or a Master’s degree in an appropriate subject. In exceptional cases, we may consider equivalent professional experience and/or qualifications. English language proficiency at a minimum of IELTS band 6.5 with no component score below 6.0.
You should ideally have a background in palaeontology, geology, or biology/zoology. Experience of experimental design and statistical analysis is desirable but not essential.
