In this episode we talk to Professor Christine Janis about mammal palaeontology, and her career. Christine is one of the world’s foremost experts in mammal palaeontology and mammalogy. She has authored dozens of scientific papers, and has been co-author of the major textbook Vertebrate Life for the last 20 years. Christine has had a long and distinguished career, and is currently a researcher at the University of Bristol in the UK. Her work is particularly focused on mammal locomotion and ecology. We’ll be talking about some of the research Christine has led, including on hoofed mammals, sabre-toothed South American ‘marsupials’, and Australia’s extinct giant kangaroos. We’ll talk about the use and limits of comparative anatomy, the importance of direct observation of specimens in the discipline of palaeontology, and how things have changed for researchers during her lifetime.
