“Every feature that is known to exist in every bird universally accepted as such is also found on dinosaurs: four-chambered heart, fused caudal vertebrae, gastroliths, even the avian respiratory system have all been found on fossil theropods, especially dromaeosaurs and maniraptors. You can distinguish birds among dinosaurs, but it is no longer possible to distinguish birds from dinosaurs.”

“Really the best way to understand anything about dinosaurs is by looking at living animals. You look at birds and then look at the closest living ancestor of birds, which is the crocodile. If you look at characteristics that birds and crocodiles have in common, the explanation is that the trait was in the common ancestor that birds and crocodiles had at one time.”

Mark Norell (1957) American paleontologist
