But that was my point - the "difference" between a dinosaur and a bird is
precisely the same as the "difference" between a mammal and a dog, or
between a vertebrate and a lungfish.  When someone asks if any known
dinosaur could do something, I assume they mean all dinosaurs, living or
extinct.  That is the standard definition in use by dinosaur specialists
today.  I wasn't trying to poke fun at anyone - a question was asked, and I
answered it.
