Re: Cretaceous "Insectivora" (was Re: No Subject)

Order Didelphiformes and other extant marsupial orders are apparently already known from the Cretaceous (and if you recognize monotremes as a single order, they do as well---but it does indeed depend on how you define "orders").
When it comes to eutherian orders, then it becomes more difficult to make a case for extant orders going back to the Cretaceous, but several of them probably did.

AFAIK, there's no compelling evidence for any modern (extant) order of mammals existing in the Cretaceous period. Of course, it does depend upon how you define said "orders"...
