Scars on the jaw of a 120-million-year-old marine reptile suggest that life might not have been easy in the ancient polar oceans. The healed bite wounds were probably made by a member of the same species. Such injuries give important clues about the social behavior of extinct sea creatures from the time of dinosaurs.
