most of the dinos were killed in the chikalub cataclisem BUT not all, the aquwatic ones have managed to survive (well some of them) and some of the land dinos as well, those evolved in to birds or changed there size to small ones like those live today '' sharks, cocks, some rare mammols also, the nutilus and few others''
now it's te age of mammols who knows mabye the next age is the one of raptiliens :)
