Gertie the Dinosaur is a 1914 animated short by animator, and cartoonist, Winsor McCay. Gertie the Dinosaur is the earliest animated cartoon to feature a Dinosaur, and was originally created as part of Winsor McCay's Vaudeville act. Gertieis the first film to use animation techniques such as keyframes, registration marks, tracing paper, the Mutoscope action viewer, and animation loops; methods that would influence the following generation of animators. Gertie is the best preserved of McCay's films, some of which have been lost or survive only in fragments, and has been preserved in the US National Film Registry. The theatrical film is a modified verson of the act, with the films initial half being a life-action, and silent, introduction.
