I was engaging in a bit of hyperbole. These articles make it sound like these creatures were like something out of a 50s horror movie, but in reality they’re about the same size as creatures living today.
Laugh, I know and was only joking, and was actually just agreeing with you, the article didn’t seem to mention the ‘prehistoric’ size, so we are free to speculate these were giant ‘Land of the Lost’ ants battling dinosaurs for their dinner in the forbidden city of the sleestaks.
