In 1980, an iridium spike in Italian clay changed the dinosaur extinction debate
A thin clay layer in Italy, discovered by a scientist and his geologist son, revealed an unusual iridium spike. This rare metal, commonly found in meteorites, pointed to an extraterrestrial event. The anomaly, present globally, became crucial evidence suggesting a massive impact caused the extinction of dinosaurs, shifting scientific focus from local geology to a catastrophic global event.
