Research - Mark Purnell
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.
More details of some of my current and recent work:
- 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)
