I am a final year PhD student investigating how different ecologies diversified throughout geological time. I analyse which ecologies were selected against in climate change driven extinction events that are similar to the current mass extinction we find ourselves in. This creates a meaningful baseline for future analysis of the effects of modern global warming - particularly when considering the stability and resilience of ecosystems as a whole rather than individual species. I perform my analyses through a suite of methods called dental topographic metrics that allow us to infer diet from 3D tooth morphology. I particularly focus on the fossil records of the first vertebrate predators a group of fish called conodonts that made up a considerable component of marine ecosystems for over 300 million years.
Chris is a palaeobiologist working to understand the interactions between life and the environment throughout Earth history. Chris addresses the critical questions of how ecologies and life modes have diversified through geological time which are most vulnerable to climate change driven extinction how resilient ecosystems are to their loss and how quickly they can recover. Chris focuses on a group of abundant and diverse jawless fish called conodonts to investigate this. He is funded funded by the CENTA NERC DTP.
Chris continues to work on projects from his previous posts including the evolution of modern fish and use of palaeocolour to reconstruct the ecologies of extinct animals.
