In this episode we talk to Jørn Hurum, Associate Professor of Vertebrate Paleontology at the Natural History Museum Oslo, Norway. Jørn has varied research interests including dinosaurs and mammals (being one of the team of researchers who described Darwinius masillae, more commonly known as 'Ida'), but perhaps his most productive work has been with the Spitsbergen Jurassic Research Group. The Jurassic sediments of the Svalbard archipelago, north of mainland Norway, are rich in fossils of marine reptiles.
