Ann Holbourn is a paleoceanographer at the University of Kiel, Germany. Her main research interests focus on the evolution and ecology of benthic foraminifera and their geochemical applications for reconstructing ocean circulation and climate change over the Cretaceous and Cenozoic. Andrew Henderson works in the oil and gas industry as a Senior Stratigrapher for Robertson, a CGG Company. After his Ph D research into Jurassic foraminifera, Andrew joined the Natural History Museum, London as a postdoctoral researcher and subsequently became a curator in the Micropalaeontology Division where he has spent most of his career. He works with most groups but has special interest in the taxonomy of agglutinated foraminifera and the biostratigraphy and systematics of benthonic foraminifera from the Middle East. Norman Mac Leod is the former Keeper of Palaeontology, and current Dean of Post-Graduate Education & Training, at The Natural History Museum, London. His main research interests include evolutionary palaeobiology, the patterns and causes of ancient extinction events, stratigraphy, palaeoceanography, and the evolution of body form in organisms.
