At the behest of a paleontological society, adventurer Howard Carpenter, heads back to the Age of Dinosaurs to scope out an anachronistic fossil, where among other things, he runs into two terrified kids from Mars and a gang of Martian kidnappers.
79,061,889 years from now, this territory would be part of the state of Montana. 79,062,156 years from now, a group of paleontologists digging somewhere in the vastly changed terrain would unearth the fossil of a modern man who had died 79,062,156 years before his disinterment—Would the fossil turn out to be his own?
