To be fair to Mr Gould, I think he's just trying to be clear, the same way
one might say "humans" are not "apes" (in the human-exclusive,
commonly-understood sense of the word "apes") since this upsets some people,
but that both are descended of a common ancestor. The analogy may appear
strained because there is no extant "dinosaur" in the popularly-understood
sense (for want of a better word, a "dragon"), which may be because the
vulgar definition seems to include their having left the stage at the K-T
Event.
