A non-evolutionary interpretation is simply that similarity in structure indicates a similarity in function. An ancestral relationship is not necessary. But many of the links had no basis in reality and were badly reasoned speculations. There is no way to guess or estimate the vocalization behavior from a fossilized skeleton. Another example came in the scene when Dr. Alan Grant and the two kids, Tim and Lex, meet a herd of gallimimus, a dinosaur similar in appearance to an oversized ostrich.
Grant remarks that the herd turns in unison like a flock of birds avoiding a predator.
Well, sure, flocks of birds do behave this way, but so do herds of grazing mammals and schools of fish. Even in an evolutionary scheme, most of the behaviors unique to birds would have evolved after the time of the dinosaurs. A contradiction to the hypothesis that birds evolved from dinosaurs is the portrayal of the velociraptors hunting in packs. Mammals behave this way, as do some fishes such as the sharks, but I am not aware of any birds or reptiles that do. The concealment of this contradiction exposes the sensational intent of the story.
