Evolution and development of vertebrate structures
This research focuses on the evolution and development of vertebrate teeth and the postcranial skeleton. It combines information from palaeontological, developmental and molecular data.
Current projects exploring the evolution of dentitions
- Early jawed vertebrate (placoderm) dentitions
Teeth and jaws: evolutionary emergence of a model organogenic system and the adaptive radiation of gnathostomes.
- Chondrichthyan dentition
Origins of the vertebrate dentition: conserved morphological development and genetic regulation of patterning in the chondrichthyan (sharks, rays) dentition. Read more in these Proceedings B and Royal Society Open Science publications.
Current projects investigating skeletal evolution
- Evolution of bone
No bones about it: an enigmatic Devonian fossil reveals a new skeletal framework - a potential role of loss of gene regulation.
- Evolution of axial skeleton
Fleshing out the fossil record: using organically preserved soft tissues to explore the evolution of unique vertebrate characters. See more on this research in the PLOS ONE publication.
- Evolution of appendicular skeleton
Evolution of paired fins and the lateral somitic frontier.
