Thomas Halliday is a quantitative macroevolutionary palaeobiologist studying the evolution of Late Cretaceous and Palaeogene vertebrates. In particular, he is interested in the diversification of placental mammals, global patterns of faunal similarity, and the methods used to answer big questions of relationships, timing, and diversity.
