 "Flesh" was a previously unconnected series about humans time travelling back to the Cretaceous era to harvest dinosaurs for their meat.Sometimes the link between two series can be of paramount importance to the story (such as Alpha's appearance in "Judge Dredd"); in other stories the reference can be a passing homage to an earlier tale with no effect whatsoever on the plot of the story in which it occurs (such as the reference to Satanus' ancestry in "The Cursed Earth").In either case, once a connection between two series was established, it was often repeated.
