Synopsis:
Professor Lang discovers the fossils of several strange animals. With Superboy's help he uncovers the fossils and authenticates them. However, the animal fossils do not match any known on Earth. When he claims they are real, the other archaeologists ruin his reputation.

Superboy believes that the animals may have come from another world. He searches the galaxy for a world that has similar traits. He eventually finds the world from which they originated. Superboy learns that the animals were brought to Earth by alien settlers. His findings restore Lang's reputation as well as the reputation of an alien archaeologist.
