About this position
This PhD studentship investigates the evolutionary affinities of some of the earliest actinopterygian “macrodont” fishes, a group of large-bodied, large-toothed ray-finned fishes that expanded during the Carboniferous after the End-Devonian Mass Extinction. The project addresses a long-standing problem in vertebrate palaeontology: how these unusual predatory forms are related to one another, how many times the macrodont body plan evolved, and what these fishes reveal about early ray-finned fish diversification.
The research will combine CT scanning of key fossil taxa with phylogenetic analysis to clarify anatomical relationships, especially in the teeth, jaws, and internal cranial skeleton. By targeting three-dimensional fossil material, the project aims to resolve whether the macrodont morphotype arose multiple times during Palaeozoic diversification. It will also compare specialisations among taxa to explore differences in ecology and feeding roles.
In addition to anatomical and evolutionary analysis, the project will compile geographic and environmental data to examine macroevolutionary patterns of dispersal, ecological expansion, and the role of macrodont actinopterygians in broader trophic networks. The work builds on emerging evidence that the post-Devonian recovery and radiation of ray-finned fishes was more complex than previously thought.
The studentship is offered through the CENTA3 DLA and is based at the University of Birmingham.
