The correlation in between the distribute of rodents as well as demise of multituberculates can be a controversial topic, not completely resolved. American and European multituberculate assemblages do decrease in range in correlation Using the introduction of rodents in these places, however the remaining Asian multituberculates co-existed with rodents without any observable replacement occurring, and eventually the two clades co-existed for a minimum of 15 million years.[ninety one]
