Collective Consciousness

Well, first he'd need to go back in time using one of my time machines, then he could hunt for the Silurian creature with the mask, then if he wanted to capture it he could use one of the many light sabers/sonic screwdrivers that I've designed to supress and capture the thing. Teleporting it back could be impossible, because for obvious dangerous reasons, teleporting a prehistoric creature back through time, to the future is strickly forbiddien and a built in fail safe device would not permit the creature to go back with it's captor. To do so would cause a rift in the space time continum and the ensuing paradox could detroy the Earth's current course and initiate an altered parallel universe to exist instead. Could get very ugly, you know.
