My research interests range across taphonomy, functional morphology, palaeobiology, palaeoecology and taxonomy, including: experimental analysis of soft-tissue character decay and preservation; developing tooth microwear analysis of feeding in fishes and dinosaurs; aspects of the taphonomy and fauna of the Silurian Eramosa Lagerstatte; and ongoing conodont projects. These projects involve collaborations with colleagues in the UK, USA, China and Canada. I supervise postgraduate research on taphonomy, palaeobiology, and tooth microwear (mainly aquatic vertebrates).
More details of some of my current and recent work:
- Deuterostome decay - taphonomic testing of fossil anatomy and phylogenetic placement (withSarah Gabbott; Research assistant - Duncan Murdock)
- Experimental decay of onychophorans - lobopodian anatomy and arthropod origins (with Sarah Gabbott; Research assistant -Duncan Murdock)
- The problem of vertebrate origins - comparative taphonomy of non-biomineralised chordates and the meaning of gaps in the fossil record (with Sarah Gabbott; Research assistant - Rob Sansom)
- Using tooth wear to impose ecological constraints on isotopic and biostratigraphic analyses based on conodonts (with David Jones (RA))
- Bridging the gap between ecological and evolutionary timescales: tooth wear, niche differentiation and speciation in living and fossil fishes (with Paul Hart, Biology)
