Gertie the Dinosaur/YMMV


 * Hilarious in Hindsight: At one point a four-winged dinosaur-dragon thing flys by. Years later, Microraptor is discovered...
 * Gertie herself is also a pretty active, lively thing. Of course, at the time paleontologists argued that dinosaurs (especially the long-necked sauropods) were nothing more than dumb lummoxes who spent their lives wallowing in swamps. While we now know that sauropods weren't as cartoonishly playful and intelligent as Gertie, she was still a far more accurate dinosaur reconstruction than the sluggish beasts that decorated science books and museums for decades after the short had debuted.
