Okapis have dense fur, and elephants have isolated hair and naked skin.
Tyrannosaurs (and all other dinosaurs) had either scales (definitely) or
feathers (not yet demonstrated, but I'd buy it for advanced coelurosaurs,
at least as juveniles). Scales have iridescent properties which fur or
skin do not.
[Okay, the real reason is probably a continuity error.]
