Who knows? I guess it might have something to do with the appearance of the 
placental birth and parental care in mammals. All you really need is 
differential survival rate: if more mammals survive to reproduce per 
generation than dino-birds, the mammals will in time take over, assuming they 
are competing for the same niches.
