Answers:    "The Paleocene genera Berruornis and Ogygoptynx show that owls be already present as a distinct lineage some 60-58 mya (million years ago), and presumably also some 5 million years earlier, at the extinction of the non-avian dinosaurs. This makes them one of the oldest particular groups of non-Galloanserae landbirds."
