During the Late Paleocene and around the Paleocene-Eocene boundary, there were important mammalian dispersals in Laurasia involving earliest modern mammals such as rodents, primates, perissodactyls, and artiodactyls. The placental carnivorous mammals (Viverravidae, “Miacidae”, Hyaenodontida, Oxyaenodonta) importantly took part in these dispersals. The present article shows that these latter mammals allow reconstructing faunal dispersal scenarios during the early Paleogene. Indeed, they evidenced several dispersal ways among Laurasia, but also with Africa and possibly India. The dispersal phases discussed in the present paper concern the Early Paleocene, Late Paleocene, latest Paleocene (Clarkforkian NALMA), and Paleocene-Eocene transition.
