Although not the first feature-length animated film, as is sometimes thought, it was the first cartoon to feature a character with an appealing personality. The appearance of a true character distinguished it from earlier animated "trick films", such as those of Blackton and Cohl, and makes it the predecessor to later popular cartoons such as those by Walt Disney. The film was also the first to be created using keyframe animation.

A plagiarised version of Winsor McCay's short from 1914

Two cavemen, The Duke and Stonejaw Steve, call on Miss Araminta Rockface. The hated rivals fight, and Steve wins when he throws The Duke into a pot of boiling water. A title card introduces a third rival, "our unassuming hero, Theophilus Ivoryhead." Miss Rockface invites the three men into her father's drawing room/cave, apologizing for not offering tea, since it has not been discovered yet. The Duke and Steve fight again, and everyone rushes out of the cave. Mr. Rockface notices his pot of food is empty; earlier, Wild Willie the Missing Link had eaten it. Mr. Rockface tells the three suitors they will have to procure their own dinner. Steve locates a desert quail and shoots an arrow at it, but the arrow misses the quail and happily (for Steve) hits The Duke's behind. Meanwhile, Wild Willie is still hungry and goes hunting for snakes. He finds a dinosaur's tail instead...

Sculptress Virginia May is seen making a clay model of a tyrannosaurus rex, which is animated using stop motion, and then fights a stop-motion triceratops. Although Miss May's only known relationship with the movies is this particular short, her contemporary, Willis O'Brien and his student Ray Harryhausen certainly made the field a lively one until computer animation caught up in the 1990s -- and arguably their artistry is still unsurpassed.
