This was a pretty poor cartoon--even by the standards of the day. Instead of a traditionally animated story, the animation looks much like Japanese shadow puppets. In fact, all the animation is done through silhouettes and seems lacking artistically.
The story itself seems pretty disjointed as well--perhaps parts of the short cartoon have been lost--it sure looked that way. The beginning has a segment where they talk about Darwin and show a bunch of monkey shadow puppets and in the next segment they show a dinosaur that is a circus act. Neither scene is particularly well-defined or interesting. This film is more important as a historical curio than for its entertainment value.
