A cave man gets up in the morning to walk around hitting things with his club. After knocking a huge dinosaur out cold, he uses the stiff dino's body as a saw, using the spiny back bones as the saw's teeth. He battles another Neanderthal for the prize of a pretty cave girl, but she uses a club on him after he wins.

A geologist attempts to dig under Possum's house in search of a rare stone. The rock collector manages to wreck everything in sight.

After a spaceship crashes on Earth, a giant egg rolls from the wreckage. The egg quickly hatches to reveal an alien dinosaur. Due to the Earth's atmosphere, the newly hatched alien dinosaur rapidly increases in size. The dinosaur turns its attention towards a railway township, which it attacks, causing great destruction. The alien dinosaur sees a water tower, which it commences to climb. The continued affect of Earth's atmosphere on the alien dinosaur makes the creature burn, destroying it.
