In the Upper Cretaceous unequivocal marsupials and placentals were in existence, and the early stages of mammalian evolution, which form the subject of this book, are definitely over. Hence only a brief mention of the faunas of the Upper Cretaceous will be made here. For those interested in these faunas, there is a good account and full references to the literature in Mesozoic Mammals (1979) (Lillegraven, Kielan-Jaworowska and Clemens (eds.), University of California Press, Berkeley).
