Dr T. S. Kemp is Emeritus Research Fellow at St John's College, Oxford, and a widely respected expert on the evolution of mammals. He is the author of several books widely used by students, including The Origin and Evolution of Mammals (OUP, 2005), and The Origin of Higher Taxa (OUP, 2015).
Tom Kemp is the world's senior authority on the origin and evolution of mammals, and an excellent writer to boot. I very much recommend this concise book as an apt introduction to the palaeobiology of our own peculiar branch on the Tree of Life * Dr Robert Asher, Curator of Vertebrates, Department of Zoology, University of Cambridge *
