My Research interests

range across functional morphology, palaeobiology, palaeoecology and taxonomy. Ongoing conodont projects include: developing tooth microwear analysis of feeding in fishes and dinosaurs; the evolution of complexity in vertebrates; aspects of the taphonomy and fauna of the Silurian Eramosa Lagerstatte.  This involves collaborations with colleagues in the UK, USA, China and Canada.  I supervise postgraduate research on palaeobiology, palaeoecology and taphonomy of conodonts, ornithiscian dinosaurs, fish tooth microwear, hydrodynamics and locomotion of armoured jawless fishes, and plesiosaur systematics and palaeobiology.

• 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)
