“Has the experiment failed?   Why hasn’t Doc Tom returned through the time tunnel?  “He’s hours overdue,” says Bob grimly.  “Where is he?”  “Back 80 million ears in time,” says Dr. Miller.  “Back in the age of dinosaurs.”  What has gone wrong?  Is it too late to save Pete’s father?  There is only one way to find out.  Pete and Bob must go through the time tunnel.”
