Dr Lisa Schnetz is a vertebrate palaeobiologist whose main research interests are on the (macro-)evolution and diversification of Palaeozoic fossil fishes, specifically the cartilaginous fishes including sharks, skates, rays and chimaeras. Her current research uses x-ray imaging (CT scanning) and quantitative methods to unravel the diversity of feeding structures in heterostracans, early armoured jawless fish as part of the Leverhulme funded project ‘Feeding without jaws’.
