These fossils are found in Laurasia,[86] the supercontinent made up of modern day-working day North The us, Europe, and Asia. The divergence of Glires, a clade consisting of rodents and lagomorphs (rabbits, hares and pikas), from other placental mammals happened inside a couple of million decades once the Cretaceous-Paleogene boundary; rodents and lagomorphs then radiated in the course of the Cenozoic.
As rodents colonized new territories and habitats, they diversified into differing kinds, a course of action named adaptive radiation. The opportunity to breed swiftly and feed opportunistically enabled rodents to rapidly adapt to a variety of distinct habitats.
