Laurasiatheria is a large group of placental mammals. The name comes from the area where advanced mammals evolved. This was on the northern supercontinent of Laurasia, roughly corresponding to Eurasia today plus North America. When Pangaea broke up, it split first into Laurasia in the north and Gondwana in the south.
