It’s incredible, but the most bizarre creatures found in the late Cretaceous period were anthropomorphic and at the same time resembled porcupines. Their bodies were covered with long and sharp spikes – reliable protection from their contemporaries – carnivorous dinosaurs. And yet, the chances for survival of those species were scarce: most of them mated only once in their life when their love fever overpowered the fear of the deadly spikes of the partner. Probably, we should appreciate the irony of paleontologists who named this species Homo iracundus, which translated from Latin means ‘passionate man’. It would seem there is nothing to be envious of for Homo sapiens, or is there?..
