If you'll forgive the Linnaean vernacular, I think that Jeff Hecht meant to
say something along these lines:
"It is curious that extant orders of birds seem to have originated well
before the K/T, in contrast to extant orders of mammals."

All the more reason to fast forward past the annoying lemurs that dominate
Disney's "Dinosaur".  Perhaps the chatty primates practiced time travel and
brought the grasslands with them as a reminder of the present.  ~%^(
