It appears that Helen finally managed to reach that button, and the end arrives... for the dinosaurs, not humanity. Not content with simply returning them to the past, the reversal rips their bones from their flesh, killing them all and sending them back as mangled corpses. Now we know what really caused the massive dinosaur extinction... Man. Yes, who was really the monster here?
Bonus: a preview scene from a future (unpublished) issue of the Dinosaurs Attack graphic novel. Select pages of artwork from the first issue will be forthcoming after the card set is finished.
