But what an exception! I don't see dinosaurs travelling to the moon,
painting masterpieces, pondering the meaning of existence, communicating
by e-mail, etc.
Anyway, it's unfair to compare extant clades with vaaastly different times
of origin. Dinosaurs have over had 220 million years. Hominines have had a
few million years. It's like comparing the accomplishments of an infant to
those of an adult.
Compare the success (whatever that means) of Dinosauria to that of
Mammalia, not Homininae.
