The Jurassic Cubs celebrate their return home but can not put aside the problem of the presence of Taurus in the Jurassic even though now it is a troglodyte. Unfortunately, however, the magical powers of the shaman Saùro cannot identify him so as to make it difficult to capture. In fact, Taurus, to escape from the jaws of a hungry tyrannosaur, meets the two oviraptors Rap and Tor with whom he takes refuge in a cave that, soon, proves to possess a very advanced technology. Instinctively, he puts a medallion around his neck and then, thanks to the arrival of a black meteorite and passing casually under what he will call a tele-source, he is teleported to another Era. Thus new journeys and new adventures begin to prevent the bad Taurus, who thanks to the medallion succeeds in assuming any form, to become the master of the world. Again in the future, the help of the old friend T-3000 will be fundamental. After succeeding in defeating another evil scientist of the future, Madron, they all find themselves in the Jurassic where they discover that the cave of Rap and Tor is nothing but the camper-space of the alien Gaul of the planet Raya. It will be on this planet that there is the decisive battle that sees the final capture of Taurus shrunken and ready to end in the prison of Tomorrow-City. Now everything is resolved and the Jurassic Cubs have found a new alien friend: Gaul.
