Ecological drivers and evolutionary patterns: diet, feeding, evolution and extinction in conodonts

Contact DetailsChris Stockey

Project Overview

Conodont elements represent the most complete fossil record throughout the Palaeozoic and Triassic but have been relatively understudied. By utilizing new techniques, we investigate micro-wear on conodont dentition and tooth complexity so as to assess their diet, trophic niche and feeding mechanism. By analysing conodont tooth function and diet we will investigate relationships between ecology, diversity and evolutionary patterns. As a result, differences in extinction risk and diversification between ecologies can be understood. This can be used to assess ecosystem responses to mass extinction events and throughout other periods of deep time.

Research Theme

Evolution and Past Environments

Research Questions

  1. How does diet vary between conodont taxa and throughout time?
  2. How does extinction risk vary between different trophic guilds of conodonts?
  3. How does survival and diversification vary with tropic ecology?
  4. How did ecosystems collapse and recover through the three mass extinction events that conodonts survived?
