After the extinction of the dinosaurs the mammals slowly took over the ecological niches that the dinosaurs had inhabited; as large herbivores and carnivores. The mammals also adjusted to niches that the dinosaurs never had inhabited, such as climbing, digging, swimming and flying forms. The large groups of mammals that we know today, arose already in the early Tertiary, and evolved together with the flora from forest to open grass-land. During this period, the continents got the shape and placement they have today.
